Mixed standard/internal standard of Baijiu

NXBY-01/02Mixed standard/internal standard of BaijiuDetailed introduction:
The mixed standard of Baijiu contains acetaldehyde, methanol, ethanol, ethyl acetate, n-propanol, sec butanol, acetal, isobutanol, n-butanol, ethyl butyrate, butyl acetate, isoamyl alcohol, ethyl lactate, ethyl hexanoate and other components, which can complete the quantification of 13 components at one time. The internal standard of Baijiu is n-butyl acetate.

1. Stainless steel packed column or Baijiu capillary column can be used;
2. When used in conjunction with a chromatography workstation or data processor, the detection data is convenient and reliable;
The company provides a large number of Baijiu standard solutions, and can configure various component mixed standard solutions according to user needs. It can configure 13, 15, 16, 22, 30, 46 and other parameter standard solutions.
NXBY-01/02Mixed standard/internal standard of BaijiuEstablish area method:
1. After the chromatography is turned on, open the computer and N2000 online workstation to check that the baseline is stable. Inject an appropriate amount of standard sample, and after the spectrum is produced, stop collecting and pop up to check the baseline. Record the file name of the spectrum.
2. Click:
① The method of integral area internal standard is adopted; (Area external standard method: The area external standard method is adopted)
② Select all sample spectral names in the component table (enter peak names before the corresponding retention time), drag the internal standard peak to position 1, select the internal standard peak "Yes", enter the purity of the internal standard substance, and submit successfully (OK) to correct the component content (compare with the input component content). Add the standard sample, open the standard reference solution spectral name, confirm the calibration is complete, and save it with any method name. The calibration of the component table has been completed and saved due to the completion of the * sub calculation. Just open its method when needed. (The steps for not operating the area external standard method are: 'Drag the internal standard peak to the first row and select the internal standard peak.' Yes, 'enter the purity of the internal standard substance.' The rest is the same.).
③ You can also input chromatographic conditions, display settings, edit items, etc., and store them in the above methods.
④ The above is to find the correction factor * online, and it can also be found offline. The steps are the same as online, but when saving the method, you need to click "Output Save".
3. Sample analysis:
① Open the method used online (as saved above), which defaults to this method every time the workstation is turned on and off.
② In the internal standard method, a certain amount of internal standard should be added to the sample. Enter the purity of the internal standard substance in the composition table and click 'submit successfully'. Click 'OK'. Inject an appropriate amount of sample and start the collection button or click 'collect data'.
③ After the sample spectrum is generated, click to stop the pre collection to obtain the analysis results. (You can also set a stop time in the sampling control to automatically stop)
