3 Gas chromatography operating conditions
Column box temperature: initial temperature80Maintain it5minAfterwards, to25/minThe rate of heating up to200 maintain5min
Vaporization chamber temperature:200Temperature in the testing room:210 Injection volume:0.2μL
Column front pressure: 100 kPa; Split ratio: 1:60

The operating conditions can be adjusted appropriately during operation based on the specific performance of the instrument.

4 Sampling method: according toGB/T6680-2003Sampling rules for liquid chemical products - Sampling.

GC-2010Type gas chromatographDetailed information:

1.High cost performance ratio, complete dual air circuit design: can be installed simultaneouslyFIDTCDFPDperhapsFIDTCDECDThree detectors can be installed simultaneously, including one packed column and one capillary column, as well as optional types such as dual capillary and dual amplifier. Choose from five detectors and methane converters, ceramic or quartz nozzles.

2Adopting brand new doubleCPUDesign, original Japanese high integration electronic circuit technology,Excellent reliability and anti-interference ability,The precision of temperature control has reached0.1, with higher display accuracy0.01And it can simultaneously display the power consumption percentage of each heating part. Six channel temperature turbidity automatic alarm and automatic power-off protection function.
3.Computer full control,Digital communication; Large screen LCDLCDDisplay; Menu based operation; Stage programmed heating system; Automatic rear door for rapid cooling; Near room temperature operation;6Road temperature control; Fault self diagnosis over temperature protection,10Complete functions including file storage, stopwatch timing, and over temperature protection
4.The detector adopts a modular design, which has the characteristics of high sensitivity, low noise, good repeatability, and wide linear range.
