UV-VISIBLE ANALYSIS of MICRO-SAMPLES absorption/emission/interference ,153
Ultra-Microspectrophotometer and Scanning
Microdensitometer
Using microscope optics to view the specimen and to coliimate the light beam, this versatile dual beam scanning-recording instrument extends the range of spectral analysis and densitometry to microspecimens far beyond the capabilities of previously available equipment. One basic instrument, with appropriate illuminators, optics, stages, accessories, and alternative readout systems, provides for all applications and covers both the U.V. and the visible. TYPICAL APPLICATIONS Forensic • blood traces • paint particles • tissue particles • ink analysis
Biochemical • cytochemical studies • natural or stained fluorescence in tissues • clinical colorimetric assays on 5-50 ul volumes • natural eye pigments • tissue extracts in picagram droplets • autoradiographs • air pollution particles • micro-electrophoresis strips Industrial • diamond crystals • powder colorimetry • phosphors • glass composition • contaminant particles • drug reactions • pigment particles • fibers and films
Film Densitometry • ultracentrifuge U.V. films • electron micrographs • diffraction patterns • micro-electronic circuitry • aerial photo interpretation Write for complete details:
