The Central Salt and Marine Chemicals Research Institute (CSMCRI) has developed a low cost fluorimeter. This device provides emission measurements at pre-set excitation wavelength by laser diode, displays sample emission counts, and concentration reading post calibration.
It has four operation modes:
- Calibration: offers 5-point calibration for user defined analyte concentration, and preset calibration data.
- Measurement: display of emission counts of sample and concentration reading (in µM) of unknown samples post calib
- Time Scan: offers 30 min trend of emission counts vs. time.
- System: displays system health parameters like CPU voltage, laser diode operating current, temperature, and laser diode ON/OFF status/control.
The fluorimeter has the ability of sample excitation at 405 nm, 450 nm, 488 nm, 520 nm by swap of laser diode; although other wavelengths can also be provided. The device operates with 12Vdc power supply, hence 12V battery can directly be used for powering the device. Device can be tailored for specific applications.
This device can be a substitute to commercially available costly scanning fluorimeters for diverse range of applications related to medical, biological, food, drug, agro, colleges etc. It has the TRL of 4.
