The atomic ratio between C, H, O, and N in an ordinary organic compound and a metal organic chelate compound could be simultaneously and satisfactorily determined by the use of 30–130 μg of a sample which cannot be accurately weighed by a microbalance or an ultramicrobalance. This was done by adopting the following modifications: 1) The amount of S was reduced to 0.5 mg from the 5 mg used in the previous studies; 2) the stainless steel column in the gas chromatograph was replaced by a Teflon column; 3) the poly(vinyl chloride) and silicone rubber tubes were replaced by stainless steel and copper tubes; and 4) a correction procedure was established for the analysis of a small amount of a sample.
