Fully automatic secondary thermal desorption instrument

ATD-804 seriesFully automatic secondary thermal desorption instrumentMain functions and features

■Fully automatic secondary thermal desorption instrumentSample grade: 100 digits

The fully automated system is safe and reliable, and does not require personnel to be on duty

■ Strong universal performance: can be used in combination with all brands of gas chromatographs (GC) and gas chromatography-mass spectrometry (GC-MS)

The sample sequence table in operation can be dynamically edited, with the ability to add, remove samples, or adjust methods

Adsorption tube, injection valve, transfer tube, and focusing tube (cooling, heating) can all be individually controlled for temperature. There are 10 methods for editing, storing, and calling at any time, and one click automatic completion of sample analysis

The cold trap adopts semiconductor refrigeration+air cooling,lowThe refrigeration temperature can reach -40 ℃ (at room temperature of 20 ℃), and the cold trap is electronic refrigeration with innovative waterproof design to avoid instrument damage caused by short circuits in the heating system

The capture trap supports multiple fillers and various modes such as pre analysis, pre heating, and Peltier cooling

The sample pipeline adopts imported silane treated inert stainless steel pipes and imported solenoid valves to reduce residual pollution

The sample transfer tube, injection valve, and focusing tube have automatic blowback function, which avoids cross contamination of different samples

■ Standard configuration includes 1/4 "diameter, 3.5" length stainless steel thermal analysis tube, adsorbent packing Carbograph2/Carbograph1/Carboxen, TenaxTA, and supports multiple specifications of analysis tubes to choose from

■ Integrated adsorption tube activation function, the system can automatically analyze the aging of the tube and achieve 100 position continuous aging. You can choose to age each sample tube immediately after testing, or batch age the sample tubes

Allow for the addition of samples twice during the experimental process without the need for resetting or interrupting the original experimental sequence, flexible and convenient. The analytical tube adopts an airtight metal chamber design, and emergency samples can be added

■ Equipped with adsorption tube pre blowing function (for sampling environments with high humidity), it prevents water vapor from entering the focusing tube of the thermal desorption instrument and the chromatographic column of the GC, effectively protecting the instrument and equipment

The transmission line connection method is directly connected through the injection port, and conventional injection and thermal analysis injection can be quickly converted. No need to connect the thermal analysis transmission line and gas-phase capillary column through an additional two-way structure, avoiding the complexity of manual operation and connection leakage problems when switching between injection methods

Support the installation of AFC/EPC intelligent system to achieve precise electronic control of gas flow

■ Support the installation of sample diversion function modules, allowing for arbitrary setting of diversion ratios to meet the testing needs of occupational health samples and high concentration samples from fixed pollution sources in the standard. It can comprehensively protect the capture trap and gas phase system, avoiding residual problems caused by high concentration sample contamination

Equipped with power on self-test and periodic self-test functions, with fault alarms and prompts, temperature overload protection function, leakage protection function, improving the safety factor of instrument use.
