Introduction
Introduction

Injection Port

Flow Controller

Detector

Data Processor

Electric Signal

Column Oven

Gas Cylinder

Column





Carrier gas and detector gas
Carrier Gas and Detector Gas

Carrier Gas and Detector Gas

Carrier Gas

He and N2 are usuallyused.

(In the case of a capillary column, helium is desirable)

The gas of 99.999% or more of purity is used.

Detector Gas

TCD ... No need

FID ... H2, Air

ECD ... N2(In the case of a packed column, carrier gas is surely N2.

In the case of a capillary column, N2 is used for makeup gas. )

FTD ... H2, Air

FPD ... H2, Air

BID ... He
