Workshop – Automated SPE on potable water using GC-QqQ
Posted on May 22nd, 2013
Metaldehyde is one, NDMA is another.
Analysing for these two compounds is rather challenging due to the limited options available for extracting these volatile and highly polar compounds from water.
Our applications team have completed initial validation on a Metaldehyde enrichment method and are close to completing a similar enrichment method for NDMA.
One of our aims has been to identify a single hardware configuration that can be used for both of these two compounds with the potential for us to devise methods for other compound classes as they appear on the horizon.
This should help labs to get the best use from their instrumentation.
In each case, the extraction is performed automatically by optimised solid phase extraction, using a dual head, GERSTEL Multi-Purpose Sampler. Once the extraction has been performed, a portion of the extract is injected into an Agilent 7000 GC-Triple Quad with EI source. This gives a seamless extraction and analysis that needs little operator involvement.
Automating the extraction locks down the process and greatly improves precision, due to the elimination of human factors.
This application note gives you some idea of what we can do to analyse for metaldehyde in water. (We will be publishing an extended application note on NDMA shortly).
We are running workshops on this topic on Wednesday 3rd and Thursday 4th July. In addition to covering our new metaldehyde method, we will also include our work on the automated analysis of NDMA, which we are able to run successfully on the same instrumental set-up, without any hardware changes.
These workshops are one-day events, conducted by Paul Roberts and Dan Carrier, and held in our Cambridge laboratory. The cost is £45 + VAT, inclusive of lunch, refreshments and all course material.
