If the bands have significant intensity (i.e. The spectrum should show weak bands from water vapor (3000-3500 cm -1, 1600≡750 cm -1 and below 400 cm -1) and CO 2 (twinned peak around 2350 cm -1). Obtain a background IR spectrum by clicking the icon B in the upper left corner of the screen. Allow the sample compartment to purge for some time. Make sure that the lid of the sample compartment is closed. It can be changed to absorbance units by clicking the mouse.īackground spectrum. The bottom half of the window is for selecting the vertical axis (%T is default). In the measurement program, go to Measurement-Parameter-Standard. You can choose whether your spectra are plotted with the y-axis as absorbance or as % transmittance (%T). The resolution is set to 4 cm -1 as default. The menu pops up with scan times: 16 (default). In measurement program: go to Measure-Parameters-Standard. To change the range, go to Settings-measurement range. For most of the applications, the suitable range is thus 400 to 4000 cm -1. Note that unless the instrument purge is quite rigorous, there will be considerable spectral interference from water vapor below 400 cm -1. A better resolution usually leads to very noisy spectra under those conditions. This will be good enough for most standard measurements. The preset parameters are 16 scans with 4 cm -1 resolution and a measurement range of 250≤000 cm -1. Go to ( Measure-parameter) and read in the default file (default.pr). You will first have to use the spectra measurement program. Start the spectra manager from the desktop screen on the computer. NOTE: PLEASE DO NOT OVERWRITE THE DEFAULT FILE SETTINGS! Make sure that the IR spectrometer has been turned on. Customer cannot modify any Approved data and methods.Īudit trail function records and archives all operations and file modifications.1. Three types of electronic signatures (Created, Reviewed, and Approved) are available. ![]() User privileges set by different security levels. Molecular weight distribution is displayed together with the calculation results and the chromatogram. The optional GPC package allows molecular weight distribution calculations. Installed as part of the ChromNAV software package, JASCO’s Spectra Manager softwear is provided to perform advanced spectral analysis.Ī powerful cross-platform software package, Spectra Manager is standard for rapid spectral scanning using UV, 4 ch-UV, Fluorescence and Cicular Dichroism detectors and data processing functions. Some useful tools for manipulating spectra, such as peak purity calculation, spectrum search, etc., are fully supported. PDA data analysis is a standard feature in ChromNAV. Peak calculation results can be sent to Microsoft® Excel automatically. Up to four channels of analog data can be acquired by each LC-NetII/ADC.ĬhromNAV includes all standard chromatography calculations, such as reliable peak integration and identification, powerful and easy quantification, a quick user-defined reporting format and versatile data conversion for data export. The LC-NetII/ADC is the hardware interface between your PC and the system components.
