WEST TUNE 930F Fluorescence Spectrophotometer
The 930F model is a variable-wavelength-adjustable fluorescence spectrophotometer, with a
standard excitation (EX) wavelength of 365 nm, an emission (EM) wavelength range of 300-700
nm and a spectral bandwidth of 12 nm.The 7-inch color touch screen applies professional
technology to empower effective human-computer interaction. The USB communication port is
used for online operation to facilitate the further calculation and processing of data and time
saving,with the universaldata processing software package, which is optional.
The instrument is widely used in biochemical, medical, food, environmental protection, chemical
and other departments for quantitative and qualitative analysis. It is an ideal instrument for
laboratory and factory inspection.
Features
The emission monochromatoradopts a 1200 g/mmgrating and a large-aperture aspherical reflector
with a particularly high sensitivity.
The high-brightness and long-lasting LED light source ensures the high stability of the test.
A newly designed sample cell holder ensures a wide variety of test methods.
The high-performance photomultiplier tube is used for the optimal signal-to-noise ratio.
Automatic zeroing and background deduction.
Real-time display of fluorescence and concentration values.
Direct reading ofsingle point standard concentration.
Multi-point linear regression can be performed at any time with the universal data processing
software package.
