Suppose we make a new compound containing of C,H, and N We probably know what it was we were trying to make That doesn’t mean we succeeded We must have evidence that the compound we made is what we wanted.

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 1760 °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 (TCD). Total C, H, and N are calculated with a precision of 0.1µg. Element ratios are more significant since they minimize instrument error. Molar element ratios may be reliably reported for up to three decimal places.
