Gas chromatograph for Baijiu analysis (used by distilleries)
Product details
Technical indexes of special chromatograph for Baijiu analysis (used by distilleries) Determination of drinking Baijiu
1： Determination of alcohol esters in Baijiu by packed column
Method principle: The method uses DNP packed column, hydrogen flame ionization detector detection, n-butyl acetate as the internal standard to quantify the alcohol ester content in Baijiu.
Determination of components: acetaldehyde, methanol, ethyl acetate, n-propanol, sec butanol, acetaldehyde, isobutanol, n-butanol, ethyl butyrate, isoamyl alcohol, ethyl valerate, ethyl lactate, ethyl hexanoate.
Detection conditions: Column temperature of 90 ℃, detector temperature of 135 ℃, vaporization chamber temperature of 135 ℃, carrier gas flow rate of 30ml/min, quantitative analysis using internal standard method. Internal standard substance
1. Large screen full Chinese display
2. Simplified Chinese menu, keyboard operation, automatic parameter memory, power failure protection
3. Equipped with fault self checking function, automatic protection and alarm for over temperature
1. Microcomputer control, high degree of automation;
2. Power on self-test function;
3. Adopting a computer-controlled rear door opening system with a small opening area, it automatically tracks temperature and dynamically adjusts the angle of the air door,Even near room temperature, precise temperature control can be achieved;
4. Overtemperature protection function: If any circuit exceeds the set temperature, the instrument will automatically power off and sound an alarm;
5. The detector adopts a modular combination design, with high sensitivity, good linearity, and a wide linear range;
6. It has wide range self diagnosis, over temperature protection, and power-off protection functions.
7. Five independent temperature control (vaporization chamber and capillary vaporization chamber can independently control temperature), with a five stage programmed temperature rise function.
8. Can be connected to various recorders, integrators, chromatographic data processors, and chromatographic data workstations.
9. This instrument is a single gas path gas chromatograph, which can be equipped with FID and TCD detectors.
Temperature control indicators of gas chromatograph for Baijiu analysis:
1. Temperature control range: room temperature+5 ℃~400 ℃ increments of 0.1 ℃
2. Temperature control accuracy: better than ± 0.1 ℃
3. Program heating: Five step constant temperature time from 0 to 999min
Increment of 0.1 minutes Temperature increment: 0.1 ℃
Heating rate: maximum 40 ℃/min below 200 ℃, maximum 20 ℃/min above 200 ℃
