Products shown here are concerned with thermal desorption instrument performance.
Focusing traps (also known as cold traps) are at the heart of all Markes’ thermal desorption instruments and perform a preconcentration function by focusing analytes to achieve maximum sensitivity. They are constructed of quartz for optimum inertness and packed with a sorbent bed up to 60 mm long and a series of sorbents of increasing strength.
Ensuring continued high performance from thermal desorption systems starts with correct set up, connection and configuration. Supplies for instrument set-up ensure an engineer or operator has everything they need to connect the instrument to the GC as well as address any areas of concern such as detecting and isolating leaks. Supplies such as helium leak detectors, tubing and connectors are fundamental for instrument set-up, troubleshooting, and optimising performance.
Standards & calibration
Calibration of the complete analytical process is of paramount importance when conducting quantitative studies. For TD analysis, additional considerations should be made regarding the loading of standards to be representative of samples, with a variety of tools available to support this.
Routine maintenance & replacement parts
Markes instruments are designed and built to enable users to carry out some level of routine maintenance themselves. Markes specialists recommend that a routine maintenance service is carried out on every TD system by a trained service engineer at least once a year. In addition, Routine Maintenance Kits are available for Markes’ instruments, which contain key supplies such as O-rings, PTFE filters, and focusing traps for ongoing user maintenance.
