Answer
Inline Calibration
Method used to calibrate ranges of very low concentrations (ppt to ppb) with an easy to handle higher concentrated standard solution. Requires a second injector and a preconcentration column.

Inline Cation Removal
MISP method to remove excess of counter ions from the sample. The sample is injected into a stream of transfer solution (typically ultrapure water). In the sample preparation module (same reaction like in suppression) the cations of the sample are removed. On the preconcentration column the analyte ions are retained and subsequently injected for analysis. Typical applications: Heavy metal removal from galvanic samples.

Inline Dialysis
MISP method to remove particles and large molecules inline from the sample solution prior to the injection. Patented by Metrohm. More efficient than Inline Ultrafiltration. Typical applications: Heavily loaded wastewater, dairy products, fruit juices, emulsions.

Inline Dilution
MIDT: It allows to automatically dilute the sample according to a set dilution factor. Liquid handling is performed with a Dosino.

Inline Eluent Preparation
EPOD: Automatic preparation of eluents for uninterrupted IC analyses for several weeks. The eluents are monitored by the Level Sensor and prepared with the Dosino ”on demand”.

Inline Extraction
MISP method for automated sample extraction e.g., extraction of ions from (bio) diesel.

Inline Matrix Elimination
MISP method to remove the matrix (disturbing components in the sample) from the analyte. The sample is injected into a stream of transfer solution (typically ultrapure water). The analytes are retained on the preconcentration column and the matrix subsequently removed by additional transfer solution. After this, the injection of the purified analytes takes place.

Inline Neutralization
MISP method to neutralize or remove excess of counter ions from the sample. The sample is injected into a stream of transfer solution (typically ultrapure water). In the sample preparation module (same reaction like in suppression) the sample is neutralized. In the preconcentration column, the analyte ions are retained and subsequently injected for analysis. Typical applications: Trace anions in NaOH solutions.

Inline Preconcentration
Preconcentration is the technology to retain the analyte on a short column (preconcentration column), which is mounted on the injector instead of the sample loop. By switching the injector, the preconcentrated analytes are introduced to the separation column. Preconcentration is mainly used for very low concentration (ppt to ppb range). It allows to collect analytes from large sample volumes.

Inline Spiking
MISP method to add a known amount of ions into a sample during preconcentration. Typical application: Check of recovery rates in a preconcentration system.

Inline Ultrafiltration
MISP method to filtrate sample solutions prior to injection. If the samples are too contaminated, Inline Dialysis might be an alternative. Typical applications: Any sample that requires filtration e.g., natural waters (surface, ground, wastewater etc.).

Metrohm intelligent Partial Loop Technology
MiPT: Partial loop injection technique making use of Dosino liquid handling. Multi-point-calibration out of one standard solution is possible. The injection volume can be adjusted to the sample. MiPT can be used for ppb to ppm concentrations.
