New HPLC Application Development Laboratory Opens
Date
1st December 2008
Over the past 6 months, Anatune has built and equipped a brand new HPLC method development laboratory.
This new lab now enables us to develop HPLC based analytical packages, in addition to GC and GC/MS based solutions we already offer. Anatune has extensive automation skills, and these transfer readily to HPLC. Several application packages have already been developed that combine fully automated sample preparation with analysis by HPLC.
Anatune has taken over responsibility from Agilent Technologies for the sales, marketing and development of trace enrichment HPLC systems based on Agilent 1200 HPLC instrumentation. As a result, our initial focus is on applications that need to concentrate large volumes of aqueous samples (1-100ml), to achieve satisfactory detection limits.
PAHs in Water
We are now able to offer a fully automated system for the analysis of PAHs in both drinking water and raw water samples. The operator needs only to pipette the water samples into 40ml vials and load them into the auto sampler tray. The system will then take over, adding standards and surrogates to each sample before loading a 10ml aliquot of the first sample onto an in-line SPE cartridge, where the PAHs are concentrated, Subsequently, the cartridge is eluted and 100% of the eluent is transferred to the main analytical column, where the target compounds are separated, prior to measurement with a fluorescence detector.
The system has been designed to comply with current UK drinking water requirements and to enable increased sample workloads to be accommodated, while requiring much less labour than existing manual practices.
Remote monitoring of acid and neutral herbicides in raw water
Anatune’s TE 100 Trace Enrichment HPLC system is the successor to Agilent’s AESOP and SAMOS on-line HPLC products and this is the application that the earlier products were developed to solve. The TE 100 is designed for remote unattended operation and can be located upstream of water supply intakes, to provide warning of the presence of herbicides in raw waters and to enable intakes to be closed until a pollution incident has passed. The TE 100 is now available in both on-line and laboratory configurations, the latter permitting the processing of large volume samples from 40ml VOA vials.
Glyphosates and metabolites in surface water samples
Work is close to completion on this project to automate the clean-up, concentration and analysis of derivatised Glyphosates in water samples using the Anatune TE 100. Glyphosate analysis is often regarded as “tricky” and it is anticipated that by automating the whole process, it will be possible to get good results as a matter of routine.
