Previous NMR analysis indicated that the compound was a para substituted ethoxy benzene. EM-600 analysis showed isotope clusters in several regions identifying chlorine, while the molec ular ion at 156 confirms the structure as p-chlorophenetole.
HERE'S JUST ONE EXAMPLE.

JOINT COMMITTEE ON POWDER DIFFRACTION STANDARDS 1601 Park Lane Swarthmore, Pa. 19081. 215-328-9400 Exhibiting: Powder diffraction patterns on plain cards, edge codeable cards, books and microfiche; data base and search programs are also available on magnetic tape.
KEVEX CORP. 898 Mahler Rd. Burlingame, Calif. This spectrum confirmed the structure of an unknown compound as p-chlorophenetole. It shows the excellent problem solving ability of the 60° sector, magnetically scanned EM-600 with multipurpose inlet. For identifications and structural analysis in the range up to 350 amu, the EM-600 gives results equal to or better than spectrometers costing much more. And the budget-fitting price lets every lab benefit from the convenience of doing its own quick analysis rather than waiting for results from a centralized analytical service. The EM-600 is one of a unified line of products from Varian Anaspect... specialist in quality instruments designed to give you more data per dollar.
