Measurement modes: Transmission and reflection
Suggested applications: Research instrument for use in all applications
Unique features: Eliminates the conventional "slit" of the spectrometer
Manufacturer: Arjae Spectral
Product name: SHEER
atomic absorption spectrometer
For: Laboratory analysis
New this year: Arjae's compact core spectrometer, slimmed down. Throughput increases of 15X or more are realistic.
