Phthalate Standards



   Chem Service Pesticide Catalogue Image      Chem Service General Catalogue Image  

Pthalates are used in many industrial and consumer products, including children’s toys, food packaging and personal care items. Due to the high potential for exposure, these products are being monitored to determine the potential risk to humans and the environment.

Chem Service has an extensive phthalate standards product line and it is growing. They offer phthalates as neat standards, single component solutions, and mixtures. Contact them for further information on custom phthalate solutions and mixtures.

Chem Service is accredited to ISO Guide 34:2009, ISO/IEC 17025:2005, and registered and certified to the ISO 9001:2015 Quality Management System for the design, development, production, distribution, and servicing of organic neat and synthetic reference materials.

Chem Service, Inc. offers the convenience, cost savings and reliability of 1,000's of Certified Standards Grade Organic Chemicals at your fingertips.

Whether your lab is big or small, disposal fees are a concern. Our products offer you the ability to have 1000's of different chemicals at quantities ranging from 100mg to 10gms; thus, reducing disposal costs.

Over 95% of our neat Standards Grade materials have a purity of 98.0% or greater, and have been analyzed by three or more (where feasible) independent methods of analysis. These do not require purity corrections when preparing a solution for use with EPA methods. Our more than 13,000 organic and inorganic standards, and solutions, support EPA Methods, ASTM Methods, State UST Methods, Air Monitoring Methods, and International Methods. We offer explosive residue standards, PCB congeners, petroleum hydrocarbon standards for the petrochemical industry, pesticide standards, FAME, and vitamin standards for food analysis.

Their Standards are precise, accurate and economical. They are ISO Guide 34:2009, ISO/IEC 17025:2005 accredited and ISO 9001:2008 certified.

Chem Service Reference Standards are supplied by Greyhound Chromatography and Allied Chemicals, 6 Kelvin Park, Birkenhead, Merseyside CH41 1LT


Q-Cap™ Capillary Columns

Q-Cap range


Our extensive range of capillary columns are designed and manufactured to the most exacting and rigorous standards. Materials of the highest quality and attention to every detail of the manufacturing process, results in columns which ensure excellent and reproducible performance for even the most difficult types of samples. Every stage of the manufacturing process, from the inertness of the highest quality fused silica tubing, the phase coating efficiency, film thickness, selectivity and low bleed characteristics of every column are all rigidly monitored. This attention to every details of the manufacturing process means you can be sure the column you purchase today will give you the same precise results as the one you purchased last year or will purchase next year.

Highest Quality Column Specifications

All Q-Cap capillary columns are manufactured under strict ISO 9001:2000 certified quality procedures, thus ensuring consistent reproducibility column after column. Every Q-Cap capillary column is individually tested to meet the most demanding performance standards, the results of which are detailed in the columns test report and installation guide.

Low Bleed

The bleed level of a column is a measure of its stability. It is directly related to the amount of stationary phase in the column and thus the film thickness. It also increases exponentially with temperature. Greyhound Chromatography Q-Cap low bleed columns have longer column lives and enable analysts to work with the latest high sensitivity detectors resulting in less instrument maintenance whilst ensuring quantification of high boiling point and high molecular weight compounds which are analysed by means of high temperature gradients.


Column efficiency is a measure of its separating power. Narrow bore columns, which have a high number of plates per meter have higher separation powers. GREYHOUND CHROMATOGRAPHY Q-Cap CAPILLARY COLUMNS This results in better resolution between two peaks or can reduce analysis time. Q-Cap capillary columns are available in diameters from 0.1mm to 0.53mmID.


The columns inertness will influence the elution and recovery of active (polar) compounds. Peak shape for more acid-base compounds improves the closer the value is to 1.0, resulting in greater quantification of peaks and more accurate and reliable results.


Reproducibility The selectivity of a column is measured by its Retention Index (RI) and indicates the elution order of the compounds being analysed. The precision manufacturing processes of all Q-Cap capillary columns ensures that the RI between them is as low as possible resulting in excellent column-to-column reproducibility.

Phase Ratio

A measure of the analytes retention time which varies according to the film thickness of the phase on the column. Columns with a small variance in phase ratio have better column to column retention time reproducibility

Susan Massie is the Sales & Marketing Director for Greyhound Chromatography and Allied Chemicals, affectionately known as 'Greyhound' in our scientific community. Greyhound was founded by Susan's husband Paul Massie more than 40 years ago, Susan hasn't been in the business for all of that time but has been involved with Greyhound for over 17 years. Greyhound continues to grow, expanding into new markets and taking on the challenges of our ever changing environment. It's heartwarming to witness the world waking up to the fact that we are damaging our planet on a daily basis. Every action we take has a direct effect on our planet and the world we leave behind for future generations. Susan is passionate about climate change and is happy to work in an industry that can have a direct effect on reducing the impact of our actions on the environment. All of the team at Greyhound take our responsibilities very seriously, the products that we supply are used by the world's leading scientists and chemists as they endeavour to monitor and repair the environment. All is not lost, if we all take responsibility for our actions, from reducing our waste and reusing or recycling our material collateral we can make a difference. The internet is full of useful advice and guidance, Susan is proud to contribute to that wealth of knowledge whenever she can.

Greyhound prides itself on personal service which provides prompt, efficient, cost-effective, safe delivery of all products. Greyhound provides technical advice and distribution of Certified Reference Standards and Materials, Laboratory Consumables, Solvents and Reagents across all scientific disciplines.
