Sample preparation in IC includes all
steps which a sample has to undergo before injection into
the ion chromatograph. This can be as easy as a dilution
step or as complex as a clean-up using several types of
solid phase extraction cartridges. Anyway whatever has
to be done prior to an injection is usually expensive
in time and materials. And it increases analysis time. |

MISP means a series of automated inline sample
preparation methods especially developed for
laboratory and online applications.
These methods allow to rationalize the time-consuming
and cost-intensive manual sample preparation steps dramatically.
A higher throughput as well as lower analysis
costs are achieved.

Automated Sample Preparation
Methods
Below you will find different applications of MISP.
Depending on the type of sample and/or matrix you can
choose out of these predefined setups. Other procedures
or combination of procedures are feasible. |

INLINE ULTRAFILTRATION |
Manual filtration using expensive cartridges
or filter caps is no longer required.
|
| Metrohm
INLINE DIALYSIS |
Allows the direct injection of difficult
samples such as latex emulsions, fruit juices, cutting
oil emulsions etc. Metrohm Inline Dialysis is more and
more becoming a standard procedure for many water laboratories.

Intelligent INLINE DILUTION |
You need to dilute your sample?
You do not know the required dilution factor?
No Problem for Profession IC!

INLINE PRECONCENTRATION |
Determination of traces of ions – or –
One of the Sample Preparation Methods below: Preconcentration
is the key.

INLINE MATRIX ELIMINATION |
Ions in water-miscible solvents?
Ions in non-ionic chemicals?
Poor reproducibility?
This is the answer!

INLINE NEUTRALIZATION |
Is your sample too acidic or too alkaline
for direct injection? Help is at hand!
|
| Metrohm
INLINE CATION REMOVAL |
Removes any interfering cations from your
samples.
|
| Metrohm
INLINE TRANSITION METAL REMOVAL |
Removes all divalent or trivalent cations
without acidifying the sample solution. This procedure
prevents poisoning of columns and membrane suppressors
that are sensitive to transition metal ions.
