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.
