Signal solar FID uses hydrogen and air combustion to generate flame as the energy source. When organic compounds enter the flame, due to the ionization reaction, they generate ions several orders of magnitude higher than the base flow. Under the action of electric field, these positively charged ions and electrons move to the negative electrode and the positive electrode respectively to form the ion flow. After the ion flow is amplified, it can be detected. FID is a universal detector with high sensitivity, which can reach (10-12 ~ 10-13) g · s-1
◆ test items: total hydrocarbon methane non methane total hydrocarbon benzene series characteristic factor

 
◆ detection limit: 0.1 ppb
 
 
◆ repeatability: < 2%
 
 
◆ analysis cycle: ≤ 60s
 

◆ air source:
 
 
Gas: high purity hydrogen (≥ 99.999%)
 
 
Carrier gas: high purity nitrogen (≥ 99.999%)
 
 
Auxiliary gas: zero level air (hydrocarbon < 20ppb)
◆ online sample enrichment desorption sample analysis automatic operation
 
◆ full remote control and feedback
 
◆ software control pressure and flow
 
◆ the low temperature cold trap of semiconductor refrigeration can be as low as - 30 ℃ greatly improving the concentration efficiency of VOCs with low boiling point
 
◆ the maximum temperature rise rate of the enrichment tube is up to 40 ℃ / s which ensures a narrow injection band width
 
◆ the pre column / back blowing technology is used to keep the target components and the high boiling point components in the back blowing sample which not only shortens the total analysis time but also prolongs the service life of the analysis column and reduces the operation and maintenance cost
 
◆ inactive and passivated pipelines and devices are used in the analysis flow path which have no adsorption on the sample and the measurement results are accurate
