What is Chromatography?

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.

Why The 'Greyhound' Brand Name?

We're often asked where our brand name 'Greyhound' comes from.  The simple explanation is that we wanted a name that people would remember easily.  38 years ago there was no such thing as Email and certainly no Internet.  Very few Fax machines were in use so everything took much longer to source and deliver.  Greyhound wanted to provide a service that was quick and reliable - there aren't many animals that are as quick as a Greyhound.  So we chose the sleek, fast Greyhound to take our business around the world.  The latest version of our logo is an 'updated' dog, probably the Great Grandson of the original dog.

Mercaptans and What They Are Used For | Chem Service | Greyhound Chromatography

Chem Service Inc Logo

WHAT ARE MERCAPTANS AND WHAT ARE THEY USED FOR?

Wine Glass

 

Mercaptans are organic compounds with a distinct odor. Mercaptans are most commonly found in as an emission from paper or pulp mills, and in coal tar and petroleum distillates. Sometimes, mercaptans can be found naturally in food, including onions, asparagus, and radishes. Mercaptans are also produced by certain marine microorganisms and produce the boggy smell that is associated with marshes. Because mercaptans can be detected by humans at lower concentrations, they can be useful odorants to help individuals detect the presence of other gasses or chemicals.

Examples of Mercaptans

There are several types of mercaptans, several of which have names more familiar to us. Examples include methanethiol, ethanethiol, 2-mercaptoethanol, cysteine, lipoamide, 2-mercaptoindole, and coenzyme A.

What do Mercaptans Smell like?

Mercaptans are effective odorants because they release strong odors that are detectable by the human nose at concentrations as small as 10 parts per billion. Most mercaptans release smells that resemble rotting cabbage or garlic. Others may smell like dirty socks or smelly feet. However, there are exceptions that smell more appealing, such as grapefruit mercaptan, which smells fruitier and more citrusy, like a grapefruit.

Using Mercaptans in Pesticides

Although mercaptans are typically used as an odorant, there are other practical uses as well. For example, methyl mercaptan is used to produce methionine, which is used as an intermediate in the production of pesticides, fungicides, and animal feed additives.

Using Mercaptans in jet fuels and plastics

Methyl mercaptan is not only used to produce pesticides but it is also used as a chemical intermediate to produce jet fuel and various plastics. Again, when used in this setting, the mercaptans is not used so much as an odorant that helps individuals detect the presence of hazardous materials, but instead, it is used to help manufacture these items.

Using Mercaptans in the synthesis of the amino acid methionine
Methionine is a unique amino acid that is found in many proteins in foods we consume. One of the biggest benefits of methionine is that it can be converted into sulfur containing molecules that can protect tissues and maintain proper cell functions in humans and animals. Although methionine is good for you, we are only exposed to it from our diet, and therefore those with a restricted diet, or large animal farms with limited raw plant materials may not be as readily exposed to methionine. However, through complex chemical processes, mercaptans can be used to synthesize methionine and supplement diets to ensure that the body gets sufficient amounts of methionine.

Using Mercaptans for Natural Gas Quality Analysis

Natural gasses often have non-corrosive mercaptans added so that humans can detect the presence of a leak or a spill. Mercaptans are also naturally occurring in some natural wells, which again, can be useful because their strong odor can help individuals detect the presence of the gasses. However, when the concentration of mercaptans is too high, there can be more negative consequences than positive ones. For instance, if the amount of mercaptans is too high, the foul smell may drive away communities. In certain cases, high levels of mercaptans can corrode pipelines, weaken their integrity, and increase the risk of significant leaks or spills. Consequently, natural gas is analyzed for mercaptan as well as other contaminants that decrease the overall quality of the natural gas. Depending on the concentration level, mercaptans may be either removed to decrease the intensity of the smell and protect the infrastructure or added to ensure that the presence of the natural gas is detectable.

How can Mercaptans be removed from Crude Oil to meet pipeline specifications?

The removal of mercaptans from crude oil can be achieved using a few different methods. One method is the use of “scavengers”, or chemical compounds that interact with the mercaptans in a manner that disables their extreme odor or their corrosive properties. Acrolein is a common scavenger because it quickly and efficiently reacts with not only mercaptans, but other harmful sulfides. The downside of using acrolein, however, is that it is extremely toxic and dangerous to use.

Another way that mercaptans are removed from crude oil by adding a substance that oxidizes them. Using a strong reagent, such as hydrogen peroxide or sodium hypochlorite can achieve the desired mercaptan levels. Additionally, adding caustic materials, such as potassium hydroxide or sodium hydroxide, can remove mercaptans. Lastly, various synthesized catalysts can be used to remove the presence of mercaptans in crude oils.

Mercaptan Extraction vs. Sweetening

When it comes to treating mercaptans, there are typically two options: extracting and sweetening. Extracting involves the process of dissolving and removing the mercaptans, typically using a caustic material. On the other hand, sweetening converts the mercaptan to remove the strong odor. The process used typically depends on what product you are trying to remove the mercaptan from. For example, extraction is typically used for lighter products, such as light naphtha, whereas sweetening is the preferred method for heavier products, including gasoline and diesel.

Why are Mercaptans and Other VOCs Important to Wine Making?

Mercaptans and volatile organic compounds (VOCs) are essential in wine making because they greatly impact two important characteristics of the wine, its aroma and its astringency. The subtle differences in these two characteristics lend to the uniqueness and complexity of various wines, giving those wines their own taste and oral sensation. Mercaptans are typically more prominent when wine has undergone the process of reduction, or during reductive winemaking. Reductive winemaking occurs when the winemaker intentionally limits the amount of oxygen the wine is exposed to while it is fermenting. The process of reductive winemaking is designed to preserve fruitiness and freshness, however, if too much oxygen is withheld, you may notice “reduced notes” in your wine, such as a whiff of rotten eggs. Decanting these minor whiffs can typically make them disappear, leaving only the desirable factors from the reductive winemaking process. However, when reductive winemaking is done incorrectly, the presence of the foul smell generated by the mercaptans lingers, and the wine is considered flawed.

How Chem Service can Help in Testing for Mercaptans

With Chem Service’s analytical standards, we help our clients identify the presence of mercaptans in their testing samples. Using our innovative products, Chem Service can help you not only identify the presence of mercaptans but also inform you on the level of concentration. We provide comprehensive testing reports that inform you of the results of our testing samples, which in turn allow you to inform your own clients on the concentration of mercaptans and make suggestions on what steps they should take moving forward. Contact us today to learn more about how Chem Service can help you test for mercaptans.

Laboratory Water | Greyhound Chromatography

Medical & Laboratory Pure Water

Q-Range Laboratory Water Product Image

Q Range Laboratory Water Suitability Chart

 

The Q-Range" of Medical and Laboratory Pure Water consists of a suite of 5 high grade pure waters, ranging from simple deionised water through to molecular biology grades, servicing the requirments of the majority of pure water laboratory uses. 

Q-Range Laboratory Water Benefits

The Q-Range™ MLG Pure Waters are suitable for the majority of laboratory reagent and molecular biology applications.

‘The majority of failed, laboratory tests are thought to be directly attributed to the impurities in the reagent water used, leading to erroneous results, added expense and delays.’

The inconsistency of source water, poor maintenance of ‘pure water’ lab systems, the lack of credible pure water standardisation/definition and the high cost of pure water all add to the financial burden which laboratories have to factor into their running costs.  

Many tests are laborious, precise and expensive to perform.   Laboratory water which is poor quality and has inconsistent purity can negatively impact the accuracy of the results by having unwanted conductivity, particles, bacteria, Nuclease or silicate levels etc.

The work involved with repeating failed test can waste many hours of analysts time further adding to the cost of each analysis.

Successful test results rely heavily on the quality

and consistency of the reagents being used.

Q-Range Pure Waters provide that important guarantee, thereby reducing costs and increasing productivity.
