The application of roller mixer in the pre-treatment stage of ICP

Advantages of the Roller Homogenizer in ICP Sample Pre-treatment

The roller homogenizer adopts a low-speed and gentle rolling homogenization method. It has significant advantages in the pre-treatment of ICP and ICP-MS trace element analysis, effectively improving sample homogeneity, test stability, and data accuracy:

The homogenization is gentle and without impact, without bubbles, no splashing, and no sample loss. It uses roller-type low-speed rolling homogenization, without generating vortices and bubbles, avoiding sample splashing, loss of volatile elements, and cross-contamination. It is particularly suitable for the pre-treatment of samples containing volatile elements such as Hg, As, and Se.

Non-contact homogenization, eliminating external metal contamination. Without contact components such as stirring rods or stirrers, there is no risk of wear, dissolution, or introduction of metal ions, meeting the strict cleanliness requirements of ICP/ICP-MS ultra-trace element analysis.

Effective prevention of sedimentation and adhesion, improving test repeatability. It can continuously and slowly roll the decomposed and diluted samples, preventing particle sedimentation and tube wall adsorption, ensuring stable sample concentration, significantly reducing test RSD, and improving result accuracy and reproducibility.

Strong batch processing capacity, compatible with various containers. It can simultaneously process multiple digestion tubes, centrifuge tubes, volumetric flasks, etc., meeting the simultaneous homogenization requirements of laboratories for large quantities of samples, significantly improving the pre-treatment efficiency.

Long-term continuous operation, supports unmanned operation. Stable, low noise, and low heat generation. It can operate continuously for a long time, compatible with sample extraction, constant temperature extraction, standard solution homogenization, etc., for long-term processes.

Can be used with a constant temperature environment, expanding application scenarios. Compact in size, reliable in structure. It can be used in constant temperature boxes / incubators, achieving constant temperature extraction and constant temperature homogenization, meeting the standardized pre-treatment requirements of samples in food, environment, geology, etc.

Summary

The roller mixer features no bubbles, no contamination, ultra-high temperature and high stability. It has become an ideal equipment for standard solution preparation, digestion liquid mixing, sample extraction and vessel cleaning in ICP/ICP-MS sample pretreatment, effectively ensuring the accuracy and reliability of the analytical results.
