Metrohm Inline Sample Preparation: Accessory sets

Accessory set for Ultrafiltration in OMNIS IC: Inline ultrafiltration allows the sample to be separated from contained particles. The main component of the Metrohm Inline Ultrafiltration system is the ultrafiltration cell. The ultrafiltration cell is suitable for sample filtration with high demands on filtration efficiency and sample throughput. This equipment is for the setup with a combination of the Peristaltic Pump Unit and the Dosing Drive Unit.Prerequisites:OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:available OMNIS Dosing Drive Unit; available OMNIS Peristaltic Pump Unit channel; available OMNIS MISP Unit; AS/ASCOOL equipped with a switching valve 3/2, UNF;

Accessory set for dilution in OMNIS IC: This technique allows samples with excessively high ion concentrations or highly concentrated sample matrices to be diluted. The required sample volume is precisely aspirated by the OMNIS Dosing Drive Unit.The sample and the dilution solution are mixed in the dilution station, ensuring the sample is diluted and completely homogenized. Additionally, with the Inline Dilution technique, calibration using a single standard solution is possible.Specifications:Maximum dilution factor: 2000; Accuracy: <1.5% up to DF 100, <2.5% up to DF 1000; Reproducibility (n=9): <1% up to DF 1000; Carry over: < 0.003%; Prerequisites:OMNIS IC S/M/L, including:available OMNIS Dosing Drive Unit; available OMNIS MISP Unit; AS/ASCOOL equipped with:dilution station and; switching valve 3/2, M6;

The main component of the Metrohm inline ultrafiltration system is the ultrafiltration cell. The ultrafiltration cell is suitable for sample filtration with high demands on filtration efficiency and sample throughput. This equipment is for the setup with a Peristaltic Pump Unit only.Prerequisites:OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:2 available OMNIS Peristaltic Pump Unit channels; available OMNIS MISP Unit;

Accessory set for the combination of dilution with Ultrafiltration in OMNIS IC: This technique allows samples with excessively high ion concentrations or highly concentrated sample matrices to be diluted. The required sample volume is precisely aspirated by the OMNIS Dosing Drive Unit.Additionally, inline ultrafiltration allows the sample to be separated from the particles it contains. This combined technique allows calibration with only one standard solution.Prerequisites:OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:available OMNIS Dosing Drive Unit; available OMNIS Peristaltic Pump Unit channel; available OMNIS MISP Unit; AS/ASCOOL equipped with dilution station and switching valve 3/2, M6;

Accessory set for Partial Loop Injection in OMNIS IC: With this technique, the 250 μL sample loop can be filled with a defined volume. The OMNIS Dosing Drive Unit, with the attached OMNIS cylinder unit, performs precise dosing steps. The intelligent partial-loop injection technique allows calibration using a single standard solution because the injection volume can be freely selected. The same applies to sample injection: a small injection volume can be chosen for a highly concentrated sample, or a larger one for low-concentration samples.Prerequisites:OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:available OMNIS Dosing Drive Unit; available OMNIS MISP Unit;

Accessory set for manual Full Loop Injection in OMNIS IC:  With this technique, the sample loop can be filled manually.Prerequisites:OMNIS IC S/M/L

Accessory set for Preconcentration Injection in OMNIS IC:  With this technique, samples at the ng/L level can be analyzed on the OMNIS IC. Inline Preconcentration uses a preconcentration column instead of a sample loop. When a precise sample volume is transferred to the preconcentration column,  the respective ions will be retained. With the injection, the bound ions flow with the eluent onto the separation column. The OMNIS Dosing Drive Unit allows calibration with only one standard solution, as the injection volume can be freely selected. The same applies to sample injection. Prerequisites: OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including: available OMNIS Dosing Drive Unit ; available OMNIS MISP Unit;

Accessory set for Preconcentration Injection with Matrix Elimination in OMNIS IC: With this technique, samples at the ng/L level can be analyzed on the OMNIS IC. Inline Preconcentration uses a preconcentration column instead of a sample loop. When a precise sample volume is transferred to the preconcentration column,  the respective ions will be retained. After enrichment of the analytes, the non-ionic components of the sample can be rinsed off the enrichment column with ultrapure water. The non-ionic sample components do not interfere with the detection of the analytes. The OMNIS Dosing Drive Unit allows calibration with only one standard solution, as the injection volume can be freely selected. The same applies to sample injection. Prerequisites: OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including: available OMNIS Dosing Drive Unit ; available OMNIS MISP Unit;

Accessory set for Full Loop Injection in OMNIS IC: With this technique, the sample loop can be filled with an OMNIS Dosing Drive Unit in combination with the OMNIS cylinder unit.Prerequisites: OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:available OMNIS Dosing Drive Unit; available OMNIS MISP Unit ;

Accessory set for Full Loop Injection in OMNIS IC: With this technique, the sample loop can be filled using an OMNIS Peristaltic Pump Unit.Prerequisites:OMNIS IC S/M/L with OMNIS IC AS/ASCOOL, including:available OMNIS  Peristaltic Pump Unit;
