NIR spectroscopy is a fast non-destructive analytical method. Almost any kind of sample can be scanned within seconds with minimal or even no preparation at all. NIRS can verify the identity of a sample and quantify multiple chemical and physical properties simultaneously.
Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.
There is no need for instrument calibration. The term “calibration” is used in NIR with two different meanings:
- Unlike other NIR instruments, the BUCHI instrument does not need to be calibrated since the accuracy is ensured by internal standards and permanent laser-aided alignment.
- In NIR spectroscopy a calibration model is generally required to interpret sample data. This model needs to be developed on setup of the application. BUCHI’s NIRCal software makes it straight forward to develop robust and reliable calibrations by correlating NIR data with reference analytics.
BUCHI’s FT technology combines accuracy and robustness. Fourier Transform spectrometers grant high wavenumber accuracy and best signal to noise ratio. Polarization interferometers are insensitive to mechanical disturbances and hence ideal for rough environments.
Yes, the NIRFlex N-500 is a benchtop spectrometer mostly for laboratory use. The NIRMaster™ and NIRMaster™ Pro provide high ingress protection and are therewith ideal for benchtop analysis at production sites. The NIR-Online™ provides analyis in real time directly on the prodcution line.
IP: Ingress Protection against dust and water
- 54: limited dust protection (5_); splash water protection (_4)
- 65: total dust protection (6_); water jet protection (_5)
While the number of parameters measurable within a calibration model is only limited by computing power and complexity of the analysis, it is common to analyze 15-30 properties at the same time.
