Shimadzu data-processor equipped Densitometers for new dimensions in quantitative TLC. • CS-920 High-Speed TLC Scanner The first instrument to make direct quantitation of TLC spots available, Shimadzu's CS-920 High-Speed TLC Scanner has a built-in integrator, printer and other technica refinements to ensure excellent quantitative analysis. Many valuable features: • The automatic lane changing mechanism permits rapid analysis of a large number of samples. Up to seven samples a minute can be scanned CIRCLE 190 ON READER SERVICE CARD
The built-in microprocessor provides automatic detection of chromatogram spots. Fused spots are separated and determined automatically. Unique high-speed zigzag scanning, working curve linearization, background correction, and reflection absorption ensure concentrationlinear output. Thus excellent quantitativeness is provided. Quantitative calculation with either the external or internal standard method. Direct printout of concentration values.

• CS-930 Dual-Wavelength TLC Scanner The Shimadzu CS-930 Dual-Wavelength TLC Scanner is a refined microcomputerized version of the Shimadzu CS-910 Dual-Wavelength Scanner—a winner of the 1977 l-R Competition. The CS-930 with parallel line printer is a low cost complete microprocessor controlled system for quantitative, highly sensitive, high-speed densitometry. The features are outstanding: • Dual-wavelength method eliminates baseline drifts caused by local irregularities of layer thickness.
• Zigzag scanning method with a very small light beam eliminates errors caused by irregular shape of developed spots. • Working curve linearization according to the Kubelka-Munk's equations. Built-in microprocessor provides: • Signal averaging-smoothing permits the quantitation of nanogram quantity level.

• Automatic lane changing up to 30 lanes of chromatogram spots. • Automatic detection of chromatogram spots. • Quantitative calculation with the external or internal standard method. The concentration values are directly printed out. • Storage of operational parameters. CIRCLE 191 ON READER SERVICE CARD

• GC-MINI2 Gas Chromatograph Compact and reliable, Shimadzu's GC-MINI2 Gas Chromatograph has a dual column flow system and on-column on-detector system. An optional temperature programmer is available for programming from the near ambient point. The three temperature sensors provide excellent repeatability in resetting initial column temperature.
• GC-8A Series Gas Chromatograph A simple construction and low cost are the key features of Shimadzu's high-quality GC. The GC-8A Series offers digital temperature setting and digital temperature programming. An on-column on-detector system, FID, constant current TCD, FPD, and ECD models are available. Circle 195
• GC-MiNi3 Gas Chromatograph The most compact microcomputerized GC with dual FID. A full performance new-generation GC with full keyboard operation. Features include an oncolumn on-detector system, m u l t i stage temperature-program capability with near ambient column temperature even with high injection port tempera s re Circle 194
Circle 192 • GC-6AM Series Gas Chromatograph The first modular designed system with sample injection port, column and detector combined into one cartridge unit— quick change of analytical conditions, elimination of cross contamination between samples and shorter down time. The only system with the complete analytical unit in the oven simultaneously. Circle 193
4 GC-9A Series Gas Chromatograph Shimadzu's GC-9A Series Gas Chromatograph with built-in microprocessor saves valuable laboratory time without loss of analytical excellence. It makes available easy user-defined programming, multiple files with linking, computer interface and generous selfdiagnostics. Now available with full detector options (FID, TCD, ECD, FTD, FPD). Circle 196 AOC-9 Automatic Sampler for GC-9A A new accessory designed to enlarge the capability of the GC-9A, the AOC9 offers sequence control through the GC-9A keyboard. Sample volume is selectable in four steps of 10,20,40 and 80% of the plunger stroke; repeat sampling for up to a maximum of 10 samples: and sample vial detection eliminating the need for batch step sample placement.
