process methods; modeling of bioseparation processes and large biomolecular structures; development of new methods such as laser ablation ICPMS for metals analysis and slurry sampling for GFAAS; and the use of image plane detection and analysis to make trace compositional mapping quantitative. Diamondstone said flow injection a n a l y s i s applications for clinical c h e m i s t r y a n d c a l i b r a t i o n standards for n e a r - I R spectroscopy are also being developed. Science a g e n c y - i n d u s t r y collaborations and especially the concept of technology transfer inevitably raise questions as to how successful the products will be and whether government can develop a technology policy, other t h a n t h a t of the m i l i t a r y industrial complex, that will actually pick w i n n e r s in t h e c o m m e r c i a l marketplace. Some academic or fundamental research institutions—notably the Scripps Clinic and Research Triangle Institute—have good working relationships with industry, but most of these relationships don't involve the federal agencies. However, the agencies have begun to promote these relationships through federal science centers such as NIST's Cold Neutron Research Facility for surface chemistry. The facility, part of the agency's reactor, came on line a b o u t t h r e e years ago, said Diamondstone, and c o n t a i n s lab space t h a t b o t h academic and industrial researchers can use for their projects. In some cases, a federal agency's p a r t i c i p a t i o n fosters t h e development of critical technologies that private companies might not otherwise attempt on their own.

atomic absorption spectrophotometry chromatography colorimetry and turbidimetry direct electrometric methods gravimetric methods measurement of physical properties reagent solutions solid reagent mixtures solvents for special purposes specifications and tests standard volumetric solutions titrimetry New in this edition are a section on determining detection limits, the general elimination of boiling point and density specifications, the use of LC in assay determinations, and a section on preparation of volumetric solutions. Twenty-four new reagents have been added. Updated methods include gas chromatography where capillary columns are now used, water determinations where coulometric methods have been added, and the replacement of flame emission techniques by atomic absorption for metal determinations. In addition, the general methods for chromatography and atomic absorption have been extensively revised to reflect their practical use in today's typical analytical laboratory. 815 pages (1993) Clothbound ISBN 0-8412-2502-8 $149.95 O R D E R
