DK-16A seriesFully automatic headspace samplerMainly used for detecting alcohol concentration in blood, residual analysis of ethylene oxide in medical devices, residual detection of solvent No. 6 in edible oil, residual analysis of acetaldehyde in PET, etc
As an analytical method, headspace analysis is first and foremost simple, as it only takes the gas phase for analysis, greatly reducing the interference of the sample matrix on the analysis As a sample processing method for GC analysis, headspace is the most convenient Secondly, headspace analysis has different modes that can be adapted to various samples by optimizing operating parameters Thirdly, the sensitivity of headspace analysis can meet regulatory requirements. After that, combined with the quantitative analysis ability of GC, headspace GC * can perform accurate quantitative analysis
Instrument features:
The headspace sampler controls the chromatograph to achieve automatic operation, continuous analysis, unmanned operation, and maximize its performance
work efficiency.
After each injection is completed, the system automatically uses inert gas to blow the sampling pipeline and quantitative ring to prevent cross contamination
Dyeing.
The inert injection channel from the injection needle to the transfer pipeline is a standard configuration of HS-16A. Obtained injection of *
System inertia.
From the sample to the instrument inlet, the entire system is heated to eliminate system cold spots, reduce sample peak broadening, and increase concentration
Distance. Make sample analysis more accurate.
Microcomputer control, LCD display, free switching between Chinese and English, membrane keyboard, numerical input,
LCD screen display: method parameter settings, real-time working status, running time, year, month, day, hour, etc.
There is a comprehensive power on self-test program, sample tray automatic positioning system, and complete fault alarm, so
Obstacle prompt function. Facilitate timely handling of problems encountered during analysis. The system pre stores a set of default analysis methods and allows
Allow users to store multiple sets of commonly used analysis methods and mixed run analysis methods.
The DK-16A keyboard allows for * control, which enables it to be compatible with all gas phase colors
