Analysis of aldehydes in water using post-column derivatization by High Performance Liquid Chromatography
In this report, JASCO extended the applicability of the method to other aldehydes by optimizing the derivatization conditions.

Analysis of total aflatoxins in food by HPLC and UHPLC
The analysis is achieved by using a derivatization method with trifluoroacetic acid (TFA) and fluorescence detection. 

Analysis of fatty acids using the Jasco LC-4000 series Rapid Separation HPLC
Measurement of fatty acids using a Unifinepak C18 column with the RHPLC system including a refractive index detector.

Thickness analysis of natural oxide film on microscopic Si pattern using MSV-5000 series
In this application the sample on which Si patterns of 35 μm widths are lined up on Ti substrate with 14 μm intervals was measured as a microstructure sample.

Estimation of refractive index of monocrystalline sapphire by polarization measurement using MSV-5000 series microscopic spectrophotometer
In this application monocrystalline sapphire(measurement area size: 50 um in diameter), which has two types of crystal axis (c-axis or a-axis) and whose refractive index is already known, was measured and the dispersion of the refractive index was calculated.

Transmission measurement of volvox by using MSV-5000 series microscopic spectrophotometer
In this application volvox which has localized cellular density due to its internal daughter colonies, was measured to obtain absorption spectra and fixed-wavelength mapping.

System evaluation of Jasco spectrofluorometer FP-8500 with optical fiber
In this application note, part of fluorescent samples were measured by using FP-8500 spectrofluorometer and OBF-832 optical fiber unit.

Absolute quantum yield measurement of solution using Jasco FP-8000 series spectrofluorometersIn this experiment, some examples will be shown for the calculation of solution sample’s quantum yield of which published values from literature are known by the absolute method.

Relative quantum yield measurement using Jasco FP-8000 series spectrofluorometers
In this experiment, an example will be shown for the calculation of quantum yield of Rhodamine B when fluorescein is used as the standard sample.

Measurement of broadband spectrum
Details of the system and measurement example using automatic wide-range measurement system are illustrated.
