Three different injection modes can be utilized:
￭ Full loop injection: for full precision
￭ Partial loopfill injection: for full flexibility
￭ Pickup injection: for smallest loss of sample
The sample loop injection with pressure-assisted sample aspiration =
PASA™ can be used with all three injection modes. This is a tried and tested concept which combines high accuracy with simplicity and reliability.
￭ No movement of the sample needle
￭ Reduced risk of bubbles in the sample intake
￭ No wearing or contamination of the injection port

4.2 Syringe and buffer loop
prevents the contamination of the syringe. Washing solution is required in
order to:
￭ remove the sample from the buffer loop and the sample needle.
￭ rinse the buffer loop and the sample needle.
4.2 Syringe and buffer loop
The following range of sample volumes can be covered with the various
injection modes using the 500 µL syringe, in combination with the standard buffer loop (1000 µL) and the standard sample loop (100 µL):
￭ Full loop: 100 µL
￭ Partial loopfill: 1…50 µL
￭ Pickup: 1…27 µL
The maximum injection volume is calculated in accordance with the following formulas:
￭ Full loop: injection volume = sample loop volume
￭ Partial loopfill: max. injection volume = 0.5 × sample loop volume
￭ Pickup: max. injection volume = (sample loop volume – 3 × needle vol-
ume) / 2
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
The full loop injection yields the maximum possible reproducibility < 0.3%,
but not the maximum accuracy, because the loop volume is specified as
being with an accuracy of ±10%. The minimum sample loss is 230 µL (2 ×
(sample loop overfilling + rinsing volume) for one 15 µL needle).
The partial loopfill injection yields a maximum accuracy and reproducibility
better than 0.5% relative standard deviation (RSD) for injection volumes
> 10 µL. The minimum sample loss (rinsing volume is equal to 30 µL.
30 µL is the recommended minimum rinsing volume. Smaller rinsing volumes can be programmed, but reproducibility will be reduced as a result.
The pickup injection offers maximum accuracy (the same as with partial
loopfill) and no loss of sample, but somewhat lower reproducibility,
namely a relative standard deviation (RSD) better than 1% for injection
volumes > 10 µL.

A washing cycle is performed after each injection.
Air segment with the full loop injection
A 5 µL air segment can be used in order to reduce the necessary volume
of sample solution. The air segment must be located at the head of the
rinsing volume and will not be injected.
In the case of a standard needle, the rinsing volume with air segment
must be at least 30 µL for one injection, and at least 35 µL for injections
without air segments. In the case of high-viscosity samples, larger rinsing
volumes must be programmed and the speed of the syringe stroke must
be reduced in order to improve reproducibility.

The following is to be observed for this injection technique:
Note
The air segment at the beginning of the sample segment is injected
onto the separation column.
Note
No overpressure is permitted to be applied in the sample vessel,
because the air segment would expand during the change from sample
position to transport position. This could lead to a considerable error
with respect to the injection volume of the sample.

6.2 Analytical problems
Analytical problems such as poor reproducibility and carry-over can occur
in any chromatography system. The cause is usually difficult to find. First
of all, you should attempt to determine whether the problem is caused by
the Autosampler or another component of the system.
Please take into consideration the fact that analytical problems can also be
caused by external influences such as temperature or light-sensitive sample. Make sure that the application was able to be performed previously
without problems and that no changes have been made to the system.
Some causes and possible solutions for analytical problems are listed
below. Contact your service point for additional help.

￭ Fill the standard vials with a pipette in order to ensure that any air bub-
bles that may appear can escape during filling.
￭ Do not fill sample vessels up to the edge. Doing so would cause the
sample liquid to be pressed into the air needle. This could cause a
cross-contamination of the samples and a contamination of the needle.
￭ It is important that the sealing caps and septa be air-tight in order to
prevent the formation of air bubbles and the evaporation of volatile
samples.
We recommend the following types of seals:
– For standard micro titer plates (low) sealing tape
– For deep well plates (high): pierceable sealing mats (pre-slit or
made of silicone) or sealing tape
– For vials: thin standard septa; no vials with hard caps which are
not designed for being punctured by an injection needle.
￭ If you use unsealed vials or micro titer plates, the precision of the injec-
tion will not be in accordance with the specifications.
