New Products
Series 3B dual-pump microprocessor-controlled liquid chromatograph is an improved version of the Series 3 solvent delivery module. The chromatograph offers a flow rate range of 0.1-60 mL/min with the two-pump system, and five gradient segments each with a variety of concave, convex, or linear solvent programs. Perkin-Elmer 401
Chromatograph
Series 2000 liquid chromatograph is a basic isocratic modular unit which can be upgraded with the addition of a dual-pump gradient module and oven. A mul-tiwavelength detector (Model 2020) with 13 selected wavelengths f rom 254 to 660 nm, or a continuous variable wavelength detector (Model 2040) that operates at 190-400 nm or 390-620 nm is available. Flow rates of 0 .1-10 mL/min can be achieved, and the LED readouts monitor 15 operating parameters. Instrumentation Specialties Co. 404
Detector and Autocont ro l Module
Model LC-75 UV detector offers sensitivity of ± 5 Χ 1 0 - 4 A 1 c m units and a baseline of 1 % noise at 0.01 A 1 c m full scale at 240 nm. The instrument is permanently calibrated and is insensitive to solvent refractive index, temperature, and flow rate. Model LC-75 autocontrol module features rapid absorbance ra-tioing, push-button spectral scanning, background correction of mobile phase absorbance effects during gradient operation, and selection of optimum wavelength for each portion of the chromatogram. Perkin-Elmer 405
Pump
ConstaMetric III metering pump has continuously adjustable f low rates of 0 .1-10 mL/min at pressures up to 5000 psi with repeatability of 1.5%. Flow rates can be microprocessor controlled with other equipment. Laboratory Data Control 409
Flavor Chemistry of Animal Foods ACS Symposium Series No. 67
Roger W. Bullard, Editor U.S. Fish and Wildlife Service
A symposium sponsored by the Division of Agricultural and Food Chemistry of the American Chemical Society.
The recent revolution in animal foods has produced high quality, more palatable foods for domestic pets and food-producing animals. Now research is also being directed toward meeting the needs of threatened wildlife species as well as toward controlling their destruction of human food supplies.
Since animals cannot directly appraise food or food additives, there are many unique problems in animal flavor research that require the cooperation from specialists in many different fields. This volume covers the problems and recent advances in this field. Many domestic and non-domestic animals are discussed by specialists in organic and analytical chemistry, biochemistry, behavior, biology, nutrition, and physiology.
