ATDS-6000A Dual Channel Thermal Desorber
First, the instrument introduction
The ATDS-6000A dual-channel thermal desorber is a new type of sample pretreatment device that combines two thermal desorbers into one, which can be used by two gas chromatographs at the same time, which is economical and practical.
Second, the instrument uses and application range
The ATDS-6000A dual-channel thermal desorber can be used with all imported and domestic gas chromatographs. The minimum detectable concentration of volatile organic compounds in the environment is up to ppb. The ATDS-6000A dual-channel thermal desorber can meet the "Measurement of Benzene in Indoor Air" and "Total Volatile Organic Compounds (TVOC) in Indoor Air" in GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering". In addition to the measurement, it can also be applied to the following fields:
1. Occupational safety, industrial hygiene and environmental monitoring;
2. Rapid identification of unknown atmospheres;
3. Analysis of flavors and flavors;
4. Assessment of toxic substance accidents (when personnel can safely return to the accident site);
5. Perimeter environmental safety monitoring of chemical weapons warehouses;
6. Quality control testing in the polymer and packaging industries;
7. Evaluation of drug solvents and product purity;
8. Residue analysis of drugs and forensic samples;
9. The hospital collects the gas exhaled by the patient and detects volatile drug metabolites in the blood.
Third, the instrument features and main functions
1. Two-way thermal desorber and analog sampling integrated design, more practical and more convenient;
2. Automated design, multi-purpose, easy to operate;
3. Microcomputer control, large screen LCD display, touch keyboard, digital input, main functions are:
(1) Method parameter setting, real-time working status, and running time;
(2) Desorption furnace, injection valve and sample transfer tube, all of which are independently heated and controlled;
(3) Set the program control, press the run key to automatically complete the entire sample analysis;
(4) The method of storing 9 can be easily called at any time to realize quick start and analysis;
(5) The GC and chromatographic data processing workstations can be started simultaneously, and the device can also be started by a foreign program;
4. With external loading gas adjustment system, it can be operated without any modification and change to the GC instrument, and the original instrument carrier gas can be used;
5. Two-way thermal desorber can simultaneously perform desorption, injection and backflushing processes;
6. Through the foreign time programming, automatic de-blowing, injection, analysis and analysis of backflushing functions;
7. For the active substance analysis, an optional elastic quartz tube can be selected as the sample transfer tube;
8. Imported pneumatic components are used for key components of the drive;
9. The needle insertion is convenient, and it can be connected to all types of GC inlets at home and abroad;
10. In order to make the imported GC more convenient and accurate, the instrument is also equipped with a special interface for various imported instruments, which is convenient to connect.
Fourth, the main technical performance of the instrument
1. Sample area temperature control range:
Room temperature - 400 ° C in increments of 1 ° C, the heating power is about 200W;
2. Valve injection system temperature control range:
Room temperature - 180 ° C in increments of 1 ° C, the heating power is about 60W;
3. Sample transfer line temperature control range:
Room temperature - 200 ° C in increments of 1 ° C. Heating power is about 40 W
(For operational safety, the transfer line temperature control is powered by low voltage);
4. Temperature control accuracy:
5. Temperature control gradient:
6. Desorption recovery rate: >95% (related to components);
7. Simultaneous desorption of sample number: 2;
8. Simulated sampling flow rate: 100ml/min;
9. Backflush cleaning flow: 0-200ml/min (two-way adjustable separately);
10. Instrument size: 400 × 170 × 300mm3;
11. Instrument weight: about 15kg.
