“…Barnard (17) gives a general discussion of ion sources using electron guns, and Vauthier (317) describes an electron gun that does not require an auxiliary magnetic field for collimation. Descriptions are also given of furnace sources (37,243,326) and surface ionization sources for positive ions (5, 159) and negative ions (145). Tsukada (310) gives a detailed description of an oscillator-type source for use with a spiral orbit mass spectrometer.…”

HE broad survey of the literature of mass spectrometry T attempted in the preceding review (61) is continued in the present one on the premise of expanded mutual interests of chemists and physicists in the many fields of science t o which mass spectrometry contributes. An effort has been made to include papers, especially of foreign origin, published too late t o be included in the previous review.Activity in mass spectrometry continues to increase in scope and intensity. Aside from the magnitude of the present review, comprehensive accounts of the theory, instrumentation, and applicatjons of mass spectrometry (16, 84, 160,208,209,230) attest to this fact. Other reviews (57, 66,149,167,181, 182, 191, 2565,257) consider recent developments and applications in varying detail, stressing for the most part chemical and isotopic analysis. INSTRUMEYTATION, METHODS AND TECHNIQUESWattauch (903,204) gives an extensive description of the various types of electrical and magnetic field arrangements used in conventional instruments for precise mass measurements. He also reports a method for determining dispersion in mass spectrography (207). The construction of a Mattauch-type mass spectrograph with a resolution of about 1/12,000 is reported by Delfosse and NBve de Mevergnies (59). Herzog (140) describes a new instrument with anastigmatic image which utilizes a combination of a spherical condenser and a homogeneous magnetic field. A new instrument utilizing no magnetic field is described b y Paul and Steinwedel (246). Miller and coworkers (212) report the development and certain clinical applications of a port-

“…type following the original design of Nier (7). Instrument I was of glass-metal construction with a source similar to that of Palmer and Aitken (9) and gave a mass resolution of better than 1 part in 220. The exit slit of the source was made 0.075 mm.…”

“…to the loss of one hydrogen atom. Neglecting second-order effects, the observed spectrum may be analytically expressed as follows: 249' = 249 -p(249) -g(249) = 249(1 -pq) (9) 251' = 251 -33(251) -g(251) + g(252) = 251 (1 -pq) + g(252) (10) 252' = 252 -p(252) -q(252) + p(251) + q( 253) = 252(1 -pq) + p( 251) + g(253) (11)…”
