What are the requirements of the gas chromatograph for the printer?

There are no special requirements for the printer equipped with the gas chromatograph. Laser printers and stylus printers can be used, but it is recommended to use laser printers, and the printed report has better results.

How to judge the cause of the failure of the full-automatic headspace sampler?

The full-automatic headspace sampler can use 10ml and 20ml headspace bottles to meet a large number of analysis requirements. The starting bottle position and the ending bottle position can be set freely to realize special requirements on site. The sample bottle oscillation function accelerates the balance time, improves efficiency, and enhances sensitivity and reproducibility. The 6-bit sample heating position can overlap heating, automatically detect missing sample bottles, and reduce the disorder of sequence analysis.

What should I do if the flow rate of the gas chromatograph cannot be adjusted?

(1) visual inspection: first check whether the gas chromatograph system has obvious sound leakage, in the gas chromatograph system gas circuit has a large leak, it is likely to lead to the flow can not be adjusted.

What if the purity of the carrier gas is not enough when the gas chromatograph is used?

How to select gas sources with different gas purity as carrier gas and auxiliary gas for operating the gas chromatograph, we suggest that under the premise of meeting the analysis requirements, gas with higher purity should be selected as much as possible, which will not only improve (maintain) the high sensitivity of the gas chromatograph, but also prolong the service life of the chromatographic column and the whole gas chromatograph (gas path control components and gas filters). However, when the carrier gas purity is found to be insufficient, in addition to replacing it with a higher purity gas, it can also be solved from the following aspects:

Operating environment requirements for gas chromatographs

In order to ensure the normal operation and use of the gas chromatograph, the use of the environment we may be satisfied with the requirements of the product, what are the specific requirements:

Maintenance and cleaning of gas chromatograph circuit board

Gas chromatograph is often used for quantitative analysis of organic matter. After the instrument is running for a period of time, due to electrostatic reasons, it is easy to adsorb more dust inside the instrument. In addition to dust accumulation, the circuit board and the socket of the circuit board are often adsorbed with some organic vapors. Because the freezing point of some organic matters is low, solidified organic matters are often found at the position of the injection port. After a period of use, the inner diameter of the shunt pipeline becomes thinner and even blocked by organic matters. During use, TCD detector is likely to be contaminated by organic matters. FID detector is used for organic matters analysis for a long time. Organic matters are deposited at the nozzle or collector position or nozzle,
