Introduction to the Well-plate Sampler
Multi-draw mode (optional)
The multi-draw mode provides injection volumes up to 1500 ul. In this case a
capillary which holds the additional volume is assembled between seat and
valve. Then the aspirated sample is pushed into the enlarged seat capillary
before repetitive aspiration starts. After the last aspiration took place the
injection valve switches and the mobile phase transports sample towards
column.
Injector program
A sequence of all available single sampling steps can be tailored to customer
needs for special applications. Injector program capability is offered with the
standard instrument
Active needle wash
The active needle wash mode allows also the flushing of the outer surface of
the needle. This results in an additional decrease of sample carry-over.
Duration of the procedure is setable.
Overlap injection cycle
Overlapped injection is the mode where the well-plate sampler runs the
injector program for the next analysis during the current analysis (without
injecting).
After the sample has reached the column the valve is switched back to bypass
and the next injection cycle starts but waits with switching to main-pass until
the actual run is finished. This mode allows it to increase the sample
throughput.
Low delay volume mode
This mode is especially interesting for gradient elution with small bore or
capillary columns. The injection valve is switched back to bypass after the
sample is eluted beyond the injection valve port # 6. This decreases the delay
volume, because the gradient needs not to pass the metering device and the
loop capillary.
