Table IV shows results from atmospheric samples collected over various time periods in Secaucus, N.J., during November 1969 and January and February 1970. The significant concentrations and percentages of C-H-N observed indicate the importance of this analysis technique to today's air pollution chemists. ACKNOWLEDGMENTThe author wishes to thank Jack Wagman of the Source Emission Measurement Methods Branch for his support and encouragement, James R. Leue of the Paxton Woods Glass Shop for his consultation and work on the modification of the quartz sample ladle, and Mrs. Ellen White of the Control Systems Division for her statistical advice.

rates many carbamate pairs. The Rf values obtained with benzene are similar to those obtained with 2-chloropropane (3) . GLC Kováts values (4) for the carbamates were recorded from short Apiezon L and DECS columns. Degradation was observed for the tertiary carbamates on the Apiezon (4) E. sz. Kováts, Fresenius' Z.
