PureSpect Manual (English version)

1. Overveiw

This chapter introduces the general information on the PureSpect operation software. The PureSpect operation software consists of the main menu of six windows as the below figure.

1.Continuation save : The window is to save a spectrum.

2.Sampling : The window is to operate various sampling functions.

3.Add index line : The window is to set various index lines in the spectrum window.

4.Reading time : The window is to control measuring conditions.

5.MP & Auto gain : The window is to overview measuring status.

6.Motor & lamp : The window is to control lamps on/off etc.

File

The File menu consists of “Save”, “Extension Mode” and “Exit” commands. The “Save” command is used when you save the spectra which is measured. The “Extension Mode” command is used when the PureSpect is needed a troubleshooting. The “Exit”command is used when you close the PureSpect software.

Parameter

The Parameter menu consists of “Automatic parameter measurement” and “Motor and lamp control”commands. The “Automatic parameter measurement” command is used when you want to check the conditions of a CCD diode array sensor. The “Motor and lamp control” command is used when you control lamps or a turn table.

Display

The Display menu consists of “Drawing line”and “Error display”commands. The “Drawing line”command is used when you want to draw index lines in the spectrum window. The “Error display”command is used when you check error messages which are occurred by a trouble in the PureSpect software or instrument.

2. Operation

2.1. Select parameter

The “setprm2”icon is displayed in the Windows

desktop menu. Click on this icon to start the

PureSpect software.

If the login dialog box is opened, select “Parameter

file” in the drop-down list. The name of parameter file

is a “Parameter-SPC” for your spectrometer. A Saika

TIF service technician has configured your copy of the

PureSpect software to match your spectrometer when

your spectrometer was installed.

Click on the “PureSpect start”button and the

PureSpect main window opens.

New

If you want to create a new parameter file, click the “New”

icon and the “COPY”window opens. You can write a new

parameter file in the entry box. This menu is useful when you

create a new parameter file which is similar to a former file.

Phase check

You can check communication between a computer and the

PureSpect instrument, when the PureSpect software will be

started. If the icon is clicked, the PureSpect software will

start after checking whether a communication between the

computer and the PureSpect instrument is working well or

not. In this case, you can find “Under a communication test”

message on your screen during a few seconds.

Offset file reading

If it is clicked, it reads a “Offset file”while starting the

program. The offset file is the data file of spectrum which was

saved when the CCD diode array sensor turned on. If you

start the PureSpect software without the offset file, you have

to pass a calculating step which corrects the Offset file when

a spectrum is converted to an absorbance spectrum for future procedures. Please, click this icon to
