Cecil Instruments’ Merit HPLC systems, in the Analysis of Phthalates

With the continuing debate on the use, contact with and effects of phthalates, a monitoring method which may be used within a processing environment, by processing staff would be useful.

Phthalates are often used as plasticisers to soften mainly polyvinyl chloride (PVC) and polyethylene terephthalate (PET).

They can be used in many types of equipment used in food processing including tubing, gloves, conveyor belts, lids, packaging, flexible plastic wraps, adhesives and inks.

Due vigilance is required for the detection and monitoring of food and beverages, particularly imports from regions which have not phased out the use of phthalates. 

Hence accurate, fast, reproducible, reliable, specific and sensitive measurements of phthalate levels are required, sometimes within the production area of the processing environment. 

Traditionally gas chromatography has been used for phthalate analyses, however HPLC (high performance liquid chromatography) may be used with a smaller degree of sample pre-treatment than that required for gas chromatography. 

Cecil Instruments’ Merit HPLC systems, lend themselves to use in the determination of phthalate levels, within a production environment.  These systems include a UV/Visible detector, binary gradient pump and integral chromatography control and acquisition software.

Within the production area, staff may perform sample pre-treatment using a simple metal compartment homogeniser and a glass based, solid phase extraction system.

The subsequent HPLC analysis method is fast, reliable, comprehensive, sensitive, specific and accurate.  The simplicity of use and low capital costs, of the Merit HPLC systems, enable staff to monitor processes quickly at the time and place of production.
