1 Introduction
1.1 Description
The IC-Ausrüstung: MiPT expands your ion chromatography system to
include the Metrohm intelligent Partial Loop Injection Technique (MiPT).
This technique allows you to fill the 250 µL sample loop with a precisely
measured volume. In this process, an 800 Dosino with a 2 mL dosing unit
performs the precise dosing increments. MiPT enables calibration with
only one standard solution, as the injection volume can be freely selected.
The same also applies to sample injection, so that you can for instance
select a small injection volume for a highly concentrated sample.
The sample needle is rinsed with ultrapure water in the rinsing unit of the
Liquid Handling Station (6.2841.120) after each sample aspiration. The
Liquid Handling Station (6.2841.120) can be mounted on any Sample Processor equipped with a Swing Head.

2.3 Mode of operation of intelligent Partial Loop Injection
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
2.3 Mode of operation of intelligent Partial Loop Injection
1. At the beginning of the determination, the Dosino's 2 mL dosing unit
is emptied.
2. Aspirating sample
a. The sample (or the standard solution) is aspirated with the 2
mL dosing unit into the transfer capillary.
b. The Sample Processor needle is moved to the waste position
(outer area of the rinsing unit).
3. Filling the sample loop
a. The injection valve is switched to the Fill position.
b. The 800 Dosino doses the injection volume from the transfer
tubing to the 250 µL sample loop.
c. Excess sample is transferred to the needle and discarded over
the waste position.
4. Injecting and rinsing
a. The injection valve is switched to the Inject position. The sam-
ple is injected into the separation column with the eluent.
b. At the same time, the Sample Processor needle is moved to
the rinse position (inner area of the rinsing unit) and cleaned.
