NS30 and Stability Tests Using the New Anatune VOC Analyser

Martin Perkins

23rd November 2017


Volatile organic compounds (VOCs) are routinely analysed in drinking and waste water using static headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS). The Anatune VOC Analyser which features autospiking of internal standards and enables high throughput using a customised 240 position tray and the PrepAhead option in Maestro software is outlined in application note AS138. This application note details an extension of that work to include 3 batches of the required 11 for NS30 procedure for VOC analysis in soft, medium, hard and surface water as well as a 7-day stability trial in spring water. The methods showed good linearities with all correlation coefficients r² above 0.995. Reproducibility experiments %rsd all below 10%, recoveries were between 92 and 107% and 7 day stability within required ±20%. Results demonstrate the suitability of the Anatune VOC analyser for analysis of VOCs in a range of water types.
