ProStar 430 Autosampler Control Manual - 17 - 03-914947-33:2
NOTE: The temperature range for sample plate cooling is from 4 °C to 40 °C and the
maximum cooling capacity is 20 °C below ambient temperature.
Check Use air segment to inject a sample with an air segment
between the sample and the wash solvent. If Use air segment
is checked, the ProStar 430 will draw an air segment of 5 µL
before the flush volume prior to an injection. The air segment
will not be injected into the analytical system.
In case of µL pick-up injection, the sample will be preceded by
an air segment, which will be injected into the analytical
system.
Check Headspace pressure to use headspace pressure in
combination with the syringe to introduce sample into the loop.
The compressor will always be used in the wash position of the
ProStar 430. The accuracy and reproducibility of the ProStar
430 can decrease when no headspace pressure is used.
However, headspace pressure will only be useful if sample
wells are airtight.
If Skip missing vials is checked, the ProStar 430 will continue
with the next programmed vial even if a vial is not found.
Uncheck this option to stop the ProStar 430 if a vial is not
found.
NOTE: The Skip missing vials option is available only when the tray type configured in
Galaxie Configuration Manager is a 48 standard vials.
Select the Syringe speed for injections. Three choices are
available: Low, Normal and High. The aspirating speed of the
syringe used in injection modes can be adapted depending on
viscosity of samples. These values are dependent of the
volume of the installed syringe (previously configured in the
Galaxie Configuration Manager):
Syringe
100 µL 250 µL 500 µL 1000 µL 10 mL
LOW (µL/min)
125 315 630 1255 1.3 mL/min
NORMAL (µL/min)
250 625 1250 2495 2.5 mL/min
HIGH (µL/min)
375 940 1880 3765 3.8 mL/min
