DK-3001BTechnical parameters of the semi-automatic headspace sampler:
Headspace bottle specification: 20ml
Sample heating position: 9 positions (circumferential distribution)
Injection valve quantitative ring specification: 1ml
Heating range of headspace bottle: 40 ℃~200 ℃, set in increments of 1 ℃
Injection valve and quantitative loop heating range: 40 ℃~200 ℃, set in increments of 1 ℃
Heating range of sample transmission line: 40 ℃~220 ℃, set in increments of 1 ℃
The relative standard deviation (RSD) of peak area for injection is ≤ 1.5% (sample is 0.02% ethanol aqueous solution, N=5)
Can store five analysis methods
Equipped with dual communication interfaces for starting the chromatograph and data processing workstation

DK-3001BThe main features of the semi-automatic headspace sampler are:
New sampling and injection operation reminder mode, humanized design, reducing the possibility of misoperation;
A wider range of thermal equilibrium to meet the needs of high-temperature headspace analysis;
After the injection is completed, the system automatically backblows to prevent cross contamination of the sample;
The quantitative loop of the injection valve and the controllable temperature of the sample transmission line are used to avoid condensation of the sample during transmission
The large LCD screen displays all temperature, time, and sample number parameters simultaneously, making operation more convenient;
The exterior design is more in line with ergonomic requirements, with over temperature and power-off protection, making it safer to use;
The injection needle can be freely replaced, making it convenient to connect various models of GC at home and abroad
