SFT-890B

Benchtop FTIR Spectrometer

SFT-890B routine benchtop FT-IR spectrometer is self-designed seal integrated Kbr beamsplitter and high sensitivity DTGS Detector. The sample compartment can compatible with IR transmission module, Attenuated Total Reflectance, diffuse reflectance up or front, and specular reflectance, gas cell etc. The experiment involves in-situ diffuse reflectance attachment, temperature controller and other auxilliary equipment can be contained inside. This design is compact and save space.
SFT-890B is widely used for solid, liquid and gas transmission characteristics, direct measure with solid or liquid ATR diamond, ZnSe, Ge crystal no necessary press, and direct connect to gas cell fit to both high and low concentration gases, customize measure is available for one stop solution provider.

Application

FT-IR spectrometer is widely applied to IR measure modules of solid transmission, ATR reflection, and diffuse transmission etc.

• Solid Transmission

Many solid powder press
Thin film Quantitative analysis
Heating press module quantitative analysis
Transparent IR materials of various glasses, Jades, crystal materials, and material properties change

• Solid / Liquid Attenuated Total Reflectance (ATR）

Many powder sample without press for direct measure
Irregular shape sample of non-destructive measure without press
Many polymer, fiber, thin film, and high polymer sample
Many O ring, rubber sample
Many others difficult to measure by transmission

• Liquid Transmission

Seal liquid cell qualitative analysis organic solution, VOCs
Disassemble liquid cell available in change optical length for quantitative analysis
Many lubricant oil quantitative analysis
IR window film forming liquid film for qualitative analysis
