Per l'analisi di campioni discreti di piccolo volume
Misura la concentrazione di gas e vapori in campioni di piccolo volume.
Il HPR-70 è un sistema compatto di analisi dei gas adatto allo studio di campioni discreti di gas.
Overview
A small quantity of gas, usually at or close to atmospheric pressure, is sampled using an automated batch inlet. After expansion and consequent pressure drop the gas is analysed using a high sensitivity 500 amu quadrupole mass spectrometer.
Most minor components in the gas mixture can be measured at levels of 5 ppm or above.
