Jilin dual channel water quality analyzer Introduction:
Autotds vPro automatic thermal desorption instrument is a 24 bit low temperature secondary automatic thermal desorption instrument with shunt function, which can store multiple operation methods.
The electric six-way valve and solenoid valve are combined in the gas path, which can automatically complete the five processes of dry blowing (removing oxygen and water gas in the sampling tube), primary desorption low-temperature enrichment (selective split), secondary desorption, sample injection and back blowing. The primary desorption temperature, secondary desorption temperature, cold trap temperature and pipeline heating temperature can be set independently At the same time, the chromatograph and workstation can be started at the same time.  

 
Jilin dual channel water quality analyzer Working conditions:
Power supply: 220 ± 22vac, 50 ± 0.5Hz (power line ensure reliable grounding, case grounding)
Back blowing carrier gas pressure: ≤ 0.4MPa
Ambient temperature: + 5 ℃~ 35 ℃
Relative humidity: ≤ 85%

 
24 bit automatic shunt low temperature secondary Thermal desorption instrument is also called thermal desorption instrument AutoTDS-VPro Technical parameters:

  • Power: < 900va

  • Sample grade: 24 / bit (40 bit customized)

  • Temperature control range:
    One time desorption: room temperature ~ 400 ℃, control accuracy ±1℃ 
    Second desorption: Room temperature ~ 400 ℃, heating rate > 3000 ℃ / min
    piping: Room temperature ~ 220 ℃, control accuracy ± 1 ℃
    Cold trap: minimum - 35 ℃ (room temperature: 20 ℃)

  • One time desorption shunt and no shunt are available

  • Timing range: 1 second ~ 59 minutes 59 seconds

  • Timing error: < 0.1%

  • Pressure resistance of gas circuit: > 0.4MPa

  • Flow regulation range: 0-300 ml / min

  • Synchronous signal output: two 1-2 second switching values

  • Overall dimensions: height * width * length 460mm * 370mm * 700mm

  • The weight of the instrument is about 35kg


Automatic 24 bit low temperature secondary thermal analyzer Main features:


  1. Strong general performance: it can be combined with any brand gas chromatograph (GC) and (GC-MS) to realize the interconnection of control information.  

  2. Simple operation, easy to use, software control, high degree of automation: just put the sample tube into the thermal desorption instrument, all operations and control are completed by the control software, so the sample repeatability is good; the design of large touch LCD screen in the host can track the temperature and operation command in the whole process.

  3. The system can store up to 10 running methods.

  4. Synchronous interface is provided to start chromatography and workstation at the same time of injection.

  5. Electronic flow display, purge flow and back flow

  6. The lowest refrigeration temperature is - 35 ℃ (room temperature is 20 ℃), which can meet most of the requirements of low temperature enrichment.  

  7. The trap is heated by direct resistance, and the heating rate is more than 3000 ℃ / min.

  8. All pipelines and six way valves can be heated at controlled temperature to eliminate the cold point of the system and reduce sample loss.

  9. Split / no split, one-time desorption can be switched between split and no split, the split ratio is manually adjusted.  

  10. With sample tube automatic leak detection and fault alarm function: before testing each sample, it can automatically check whether the sample tube and system gas path are installed properly.  

  11. The sample pipeline is treated with silylation inert treatment of stainless steel pipe to reduce pollution residue.

  12. It is directly connected to the GC carrier gas path without occupying the injection port.

  13. No pneumatic components, no need to drive air source.
