Instrument features:
Adopting negative pressure sampling mode, the headspace bottle does not require gas replenishment, and the sample has no dilution effect of external gas, resulting in high sensitivity.
Overlapping preheating automatic injection mode reduces manual intervention and improves analysis efficiency.
After injection, the system automatically blows back the hot air flow to avoid cross contamination and system residue between different samples.
The sample heating furnace adopts a metal thermal conductor, which has a large heat capacity and high temperature stability. The preheating holes are distributed around the circumference, minimizing the temperature gradient between different hole positions and improving the analysis accuracy.
The LCD display screen simultaneously displays the equilibrium temperature, preheating time, injection interval, method number, and stores 6 sets of methods, making it easy to operate.
The injection needle can be freely replaced, making it convenient to connect various models of GC at home and abroad.
