Shimadzu SPD-M10Avp/M20A PDA Detector: Program Example

The following program section shows examples for sampler and pump settings as well as the relevant settings for any important PDA parameters:

; ===============================================

; Sampler settings (Example, may vary depending on sampler type)

; ===============================================

 DispSpeed =  10.00 [µl/s]

 DrawSpeed =  10.00 [µl/s]

…

; ================================================

; Pump settings (Example, may vary depending on pump type)

; ================================================

 Flow =   0.000 [ml/min]

 %B =   0.0 [%]

 %C =   0.0 [%]

 %D =   0.0 [%]

… 

; ===============================================

; Detector settings

; ===============================================

; Temperature (if available, SPD-M20A only)

 TempCtrl =   On

 Temperature.Nominal =  40 [°C]

; General device and signal settings

 Data_Collection_Rate = 6.25000 [Hz]

 Response =  160 [ms]

; Slit width (available for SPD-M20A only)

 SlitWidth =  1.2 [nm]

; 3D field

 3DFIELD.MaxWavelength =  600 [nm]

 3DFIELD.MinWavelength =  200 [nm]

 3DFIELD.BunchWidth =   4 [nm]

 3DFIELD.RefWavelength =  Off

 3DFIELD.RefBandwidth =  1 [nm]

; Single channel – Signal properties

 UV_VIS_1.Wavelength =  254 [nm]

 UV_VIS_1.Bandwidth =  4 [nm]

 UV_VIS_1.Step =  Auto

 UV_VIS_1.Average =  On

; Single channel – D/A converter board settings (if available))

 UV_VIS_1.Range = 4000 [mAU/V]

 UV_VIS_1.Polarity = Positive

; Add parameters for any further channels here

; if required

 …

0.000 3DFIELD.Autozero 

 UV_VIS_1.Autozero

 Wait UV.Ready and Sampler.Ready

 Inject

 3DFIELD.AcqOn

 UV_VIS_1.AcqOn

; Autozero commands can be added during a run

; if required

5.00   3DFIELD.Autozero 

10.000 3DFIELD.AcqOff 

 UV_VIS_1.AcqOff

 End

Special hints if start of data acquisition is triggered by an external signal

If start of data acquisition is controlled by an external hardware signal, observe the following:

• In  manually edited PGM files, make sure that the Wait command line includes an UV.Ready segment (Wait UV.Ready).

• Manual data acquisition can be performed with the Start with hardware signal option enabled. In this case, however, acquisition is started by Chromeleon and not by the detector signal.

For details on how to configure the detector and enable the Start with hardware signal option, refer to  Shimadzu SPD-M10Avp/M20A PDA Detector: Installation (Device Settings section).

For information about the special commands that Chromeleon supports for controlling the detectors, refer to Commands and Tips for Third-Party Devices  Shimadzu SPD-M10Avp/M20A PDA Detector.
