The simple measurement method of liquid sample in near-IR region
In this note, Jasco introduces the simple measurement method by using the test tube with cell cap or easily washable laboratory dish, the portable type near-IR detected instrument VIR-9650 was used.

Measurement reproducibility of Color Diagnosis System
Jasco has developed various applications that use the V-700 Series of UV/Vis spectrophotometers for color analysis using both reflectance and/or transmittance spectra of samples. The V-700 spectrophotometer uses a double-beam optical system, which offers high measurement accuracy and stability. Because of the high performance of the V-700 UV/Vis spectrophotometer color coordinates (results for color calculation) can be determined with high reproducibility.

Reducing the noise due to water vapor and carbon dioxide by Sample shuttle, and the combination of Purge and Vacuum and Interval program
In this application note, Jasco introduces a couple measurement tips of Shuttle measurement and Purge and evacuation.

Fluorescence Observation, Polarization Observation and Differential Interference Observation methods are useful optional observation function
These methods are presented in this technical note.

FTIR methods of time course measurement
Jasco will show each FTIR methods' feature and measurement in this application.

Variable-angle transmittance measurement attachment with polarizer option
Jasco VAT-500i Variable-angle transmittance measurement attachment can be used for difficult applications of samples with reflectance. In this attachment by changing the incident angle of light against the sample surface, the reflected light would not go into interferometer. In fact, this design can drastically reduce the level of noise due to water vapor even the incident angle is changed as small as 10 to 20 degree.

Simple analysis of brominated flame retardants with far-infrared spectrometers
This application demontrates a simple analysis of brominated flame retardants using the full vacuum type of model FT/IR-6000 series.

Simple method for quantitative analysis of brominated flame retardants with far-infrared spectrometers
In this application, quantitative analysis results by the calibration curve in far-infrared region were compared with the results in the mid-infrared region in order to confirm the usefulness of analysis by FTIR spectroscopy.

Analysis of egg using thermal ATR
This application is an example of thermal ATR analysis performed on egg, for which water content is approximately 75%.

ATR application to granular gum by auto-contact ATR accessory for VIR-100/200/300In this application note, the auto contact ATR has been applied to the monitoring of spectral change by changing of number of contact with sample such as granular gum.
