Highly sensitive detection of DL-flavanone with circular dichroism detector
The optically active compound DL-flavonone was detected using a dedicated circular dichroism detector (CD-1595).

Analysis of amino acids using on-line pre-column derivatization with OPA with rapid separation HPLC
In this application, 19 amino acids were measured using OPA pre-column derivatization through the automated pre-column derivatization function of autosampler. The RHPLC conditions drastically reduced the measurement time.

Measurement of protein film samples in vacuum ultraviolet region by using J-1500 CD spectrometer
CD spectra reflecting the secondary structure of protein are usually observed from UV region below 260 nm to the vacuum ultraviolet region. It has been reported that by CD instrument utilizing synchrotron radiation the protein film sample was successfully measured down to around 140 nm. CD analysis by using synchrotron radiation is a very effective method to measure CD in vacuum ultraviolet region, however, it is not easy since it requires a very special facility. JASCO Model J-1500 enables to achieve high S/N CD measurement even in vacuum ultraviolet region. This note shows the analysis example of protein film sample in vacuum ultraviolet region by using J-1500 CD spectrometer.

CD measurement at NIR region by J-1500
Measurement of nickel tartrate and limonene

Verification of wavelength accuracy and wavelength repeatability using mercury emission line spectrum
In this application data, wavelength accuracy and wavelength repeatability are verified by measuring the 253.652 nm emission line spectrum of the mercury lamp, which is installed in J-1000 series CD spectrometer for validation.

CPL spectrum measurement of Green Fluorescent Protein
This application note shows CPL measurement results about GFP fluorescence protein by using CPL-300.

Full system control and real-time monitoring
The DT-810 dissolution tester is controlled by a 21 CFR 11 compliant software package. The dedicated software offers easy-to-use operation for fully-automated control and monitoring of testing processes of the whole system including the the pump, the fraction collector and the UV/VIS spectrophotometer. Powerful and user-friendly features include a validation program compliant with USP, EP and Japanese Pharmacopoeia procedures, a daily self-diagnostic function, monitoring functions of the system conditions and system status such as the bath temperature, vessel temperature and the UV/Vis absorbance of the sample, among other parameters.
