Ultimate convenience

Dual-TD is designed with the analyst’s experience in mind. Markes’ easy-to-use MIC™ software is optimized for Dual-TD, meaning only a single TD sequence needs to be configured. This saves time while ensuring that sample sequences remain synchronized with peak efficiency.

Market-leading advantages of Dual-TD

Incorporating all the innovative features of the Markes TD100-xr series, Dual-TD significantly enhances the productivity of TD–GC systems. Key benefits include:

1. More samples in less time: "Overlap mode" significantly reduces the time between injections, while run times can be further reduced by up to 40% if Hydrogen is used as the carrier gas.

2. Eliminate dependency on Helium: Multi-Gas capability 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.

3. Sample security: With quantitative sample re-collection for repeat analysis, Dual-TD simplifies method/data validation, overcoming the "one-shot" limitation of inferior TD systems. Tubes remain capped at all times, preventing contamination and analyte loss.

4. Cost savings: Electrically-cooled focusing traps eliminate the expense and hassle of liquid cryogens and maximize uptime by preventing the risk of ice blockages. Using Hydrogen also eliminates dependency on expensive Helium.

5. Wide analyte and concentration range: Dual-TD can analyze VOCs from C3 to C44, including reactive and thermally labile species. Unbeatable split versatility (from true splitless to 125,000:1) enables the analysis of both high-concentration and trace-level samples.

6. Precision: Automated addition of an internal standard to the focusing trap or to a tube during analysis enhances data quality.

7. High data quality: Automatic leak tests performed before each sample analysis ensure confidence in data quality and full compliance with key regulated methods.

8. Reliability: Dry-purge or pre-purge functions automatically remove water and air from the sample before analysis, avoiding GC interference and extending the lifetime of the column and detector.

9. Simplified chain of custody: The on-board TubeTAG read/write functionality automatically updates tube and sample information during analysis.

10. Method compliance: Stringent leak testing, re-collection, and a range of advanced water management options ensure full compliance with key standard methods from regulatory bodies including US EPA, Chinese EPA, CEN, ISO, ASTM, HSE, JSA, and NIOSH.

11. GC versatility: Compatibility with GC and GC-MS systems from all major manufacturers minimizes the upfront investment required to explore new TD markets for your lab.

12. Easy and intelligent operation: Built-in standard-method parameters, automated self-checking diagnostics, and usage/maintenance counters maximize instrument uptime.

Increased productivity with overlap mode

This graphic illustrates how using overlap mode with Dual-TD increases productivity by allowing more samples to be analyzed simultaneously within the same timeframe.
