Gas chromatography thermal desorber Dual-TD™

high-throughput

Dual-TD™ is a thermal desorption system for maximising sample throughput from a dual-channel GC, by simultaneously processing two batches of sample tubes. Featuring two TD100-xr units running simultaneously, Dual-TD instantly doubles sample throughput. It also uses ‘overlap mode’ to desorb a pair of samples while the analysis of the previous pair is still running, eliminating GC ‘idle time’. Dual-TD is compatible with any dual-channel GC, and is independently certified for operation with helium, nitrogen or hydrogen carrier gas (Multi-Gas capability). Dual-TD is ideal for high-throughput laboratories needing to: Efficiently carry out large-scale sorbent tube background testing. Undertake targeted trace VOCs and SVOCs analysis. Measure total VOC analysis at scale. Ultimate convenience Dual-TD is designed with the analyst in mind. Markes’ easy-to-use MIC™ software is optimised for Dual-TD so only one TD sequence needs to be set up. This saves time whilst ensuring sequences remain synchronised with utmost efficiency. Using all the innovative features of Markes' TD100-xr, Dual-TD significantly improves TD–GC productivity. The main benefits are: More samples in less time – ‘Overlap mode’ significantly reduces the time from one injection to the next, while run times can be further reduced by up to 40% if hydrogen is used as the carrier gas. Eliminate helium dependency – The Multi-Gas capability on Dual-TD allows you to use helium, nitrogen or hydrogen as a carrier gas for automated sorbent tube analysis. Using hydrogen significantly reduces run times without compromising analyte sensitivity or peak resolution.
