Instrument spares & consumables
For over a decade, Markes International has pioneered and commercialised enhancements to analytical TD instrumentation and associated sampling apparatus.
The following key technical advances have all been introduced by Markes since 1997 and now set the standard for TD instrumentation:
- SecureTD-Q™ (quantitative re-collection of split flow)
- Electronic tube tagging (TubeTAG™)
- Diffusion locking (SafeLok tubes, DiffLok caps)
- Patented inert valving for compatibility with every TD application on a single analytical platform; ultra-volatiles, semi-volatiles (up to n-C40) plus reactive species - mercaptans, CS gas, etc. – all on one TD system
- Automated IS introduction onto blank and/or sampled tubes
- Electrically-cooled sorbent trapping with uniquely fast trap heating rates for splitless capillary GC and optimum sensitivity without risk of ice formation
- On-line desorbers with twin, electrically-cooled, reciprocally operated focusing traps for continuous air monitoring (TT24-7)
