Computerized technique in organic microelemental analysis: Determination of C,H, N,and O

A computerized on-line system for elemental analyses of C, H, N, and O is described. Four elemental analyzers and two electronic microbalances were interfaced to the computer via scanner and DVM. Calculations of percentage composition found and theoretical were collected on two teletypes. Two technicians operated the two stations. The daily output of analyses is approximately 75 CHN analyses and 25 oxygen analyses (including standards).
