3. Gas chromatography operating conditions
Column box temperature: initial temperature80℃Maintain it5minAfterwards, to25℃/minThe rate of heating up to200℃, maintain5min;
Vaporization chamber temperature:200℃Temperature 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 simultaneouslyFID、TCD、FPDperhapsFID、TCD、ECDThree 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. 2.Adopting 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 accuracy0.01℃And it can simultaneously display the power consumption percentage of each heating part. Six channel temperature turbidity automatic alarm and automatic power-off protection function. Main technical specifications of the detector Hydrogen flame ionization detector(FID) (1)Cylindrical collection electrode structure design, quartz nozzle, responsive* (2)Detection limit:≤8×10g/s(HEXADECANE/isooctane) (3)Baseline noise:≤2×10A (4)Baseline drift:≤2×10A/30min (5)Linear:≥10 Thermal conductivity detector(TCD) (1)Adopting a semi diffusive structure (2)The power supply adopts constant current control mode (3)Sensitivity:≥2500mV·ml/mg(HEXADECANE/isooctane).
