Autodilution & Autocalibration Systems

prepFAST M5X Model

The prepFAST M5X for ICP and ICPMS is a fully integrated autodilution and autocalibration system that improves precision and detection limits while significantly increasing sample throughput, delivering additional dilution factors of 1 to 40,000x via dual-stage dilution.

Syringe Sample Loading and Extended Dilution Range

The prepFAST M5X provides both precision syringe loading of samples and high-throughput vacuum sample loading. Syringe loading is recommended when sample volumes are limited (0.1-3 mL) or when increased sample viscosity becomes an issue. This can include organic solvents, viscous brines or biological sample. Vacuum loading can be used when sample volumes are larger or when sample viscosity is not an issue.

The prepFAST M5X system is available in the following models:

P-Series FAST: 2DX, 4DX, 8DX, and 14DX
SampleSense FAST: 2DXCi, 4DXCi, 8DXCi, 14DXCi

SampleSense prepFAST Autodilution Advantages

Innovative Sample Loading

Innovative Sample Loading

SampleSense accounts for viscosity and automatically adjusts timing. One method for multiple sample types.

SampleSense prepFAST Valve Enclosure

Time Savings

Operator time for sample introduction method development is eliminated. Just run samples.

Sample Savings

Sample Savings

The sample is injected at precisely the right time. Every time. Even for small samples.

Error Notification

Error Notification

Incomplete sample loading or bubbles in the sample are detected and logged.
