Description
The PE 2400 is a conventional elemental analyzer. It operates by flash combustion of the specimen encapsulated in tin cups or disks whereby the specimen is completely combusted at a temperature of 1,760 C. The resulting gases are chemically scrubbed of the halogens (and of sulfur in the CHN mode) and are separated in a GC column. Detection is conducted by a thermal conductivity detector. Total C, H and N are calculated with a precision of 0.1g. Element ratios are more significant since they minimize instrument error. Molar element ratios may be reliably reported for up to three decimal places.
