摘要
Virtual size redn. of the sample magazine for headspace gas chromatography is achieved by replacing 'n' individual steps of the magazine by 'm' large steps of size 'ss'. In appts. for carrying out the process, the sample magazine is round and the sample locations are arranged in a circle or several concentric circles, or the sample magazine has a rectangular shape. When the sample magazine is rectangular, it pref. has a guide for linear transport of the sample holders in several directions. ADVANTAGE - Higher sample throughput is achieved, even when the needle downtime is greater than or equal to the temp. hold time divided by the number of sample locations, while maintaining the large number (n) of sample locations.
