✦ Synopsis

A simple, portable instrument for the determination of carbon dioxide concentration in atmospheric air by non-aqueous titration is described. The method can be used in the range 10-10,000 p.p.m. 50-ml air samples containing about 300 p.p.m. CO2 can be analyzed with an accuracy of +__ 39/0. With increasing sample size the accuracy increases. A simple device is used to compensate for the influence of temperature and pressure. The time required for one titration is about 2 min.

## Abstract A novel method is firstly presented for field and rapid analysis of short‐chain aliphatic amines in water as their pentafluorobenzaldehyde (PFBAY) derivative using solid‐phase microextraction (SPME) and portable GC. In the proposed method, short‐chain aliphatic amines in water rapidly r
