The working principle of the instrument:

GC-2060FFully automatic blood alcohol detectorBased on gas chromatography manufacturing, it is an effective device for implementing gas chromatography. The instrument uses gas as the mobile phase. When a multi-component mixture sample to be analyzed is injected into the vaporization chamber and instantaneously vaporized, the sample is carried by the carrier gas of the mobile phase. When passing through the chromatographic column with a fixed phase, due to the adsorption, desorption, and dissolution processes between the component molecules and the fixed phase molecules inside the column, those components with similar performance structures undergo significant separation effects due to repeated distribution of their molecules between the two phases. Moreover, due to the different adsorption and desorption forces of each sample component, the reaction time is also different, resulting in the separation of the components in the mixed sample. The separated components enter the detector system in sequence, and are converted into electrical signals by the detector and sent to the recorder, integrator, or workstation.

Product features:

1. Large screen Chinese display, easy to operate, learn and operate, with good overall stability and good repeatability;

2. The headspace heater, used in conjunction with the chromatograph, is quite convenient for sample processing and is also very expensive, solving the contradiction of the higher price of fully automatic headspace compared to the chromatograph; Select and configure various models of headspace samplers according to customer needs.

3. The whole set of instruments is of high quality and low price, and the data produced can be compared with that of any imported chromatograph. However, the price is only one tenth of that of imported instruments, and the price of the whole set of instruments is also relatively high compared to other instruments;

4. The whole machine is easy to operate and has a high degree of automation. Through the N2000 chromatography workstation, analysis reports can be easily printed on the computer, and various parameters of the analysis report can be adjusted according to each sample, making the results accurate, intuitive, and easy to label;

5. Company commitment: All users guarantee on-site installation, debugging, and sample preparation according to standards. The laboratory technician can operate the instrument and ensure its long-term normal use;

6. Equipped with a three in one generator and randomly provided accessories, the instrument also has very few consumables for long-term use.

*Advantages: Innovative design: This instrument has undergone special and exquisite design, and is economical and durable. The instrument components have been tested for a long time and are stable and durable. High cost-effectiveness: The price is only 30% to 50% of the price of similar products. Low residual adsorption: The entire pipeline is made of inert materials and heated and insulated.
