Sample Pretreatment for Optical Emission Spectrometry
Samples are taken from molten metal, thin sheet, semi-complete or complete products. When sampling molten metal with a ladle, small quantities of molten metal are poured into a casting mold. Unnecessary parts of the sample are removed using a grinder or a cutter. As particles from a grinder may contaminate the surface of the sample, a lathe or milling machine is used (not a grinder) to cut soft samples such as white metal. If trace elements are not being investigated, a grinder or belt sander can be used. However, to minimize contamination, the grinding wheel or belt should be changed for each sample. Samples excised from semi-complete or complete products must be at least 12 mm in diameter. Small rod-shaped samples can be analyzed using special equipment.

New Video: The Cabbage Core, Trash or Treasure?
Most people throw out the cabbage core when cooking, but is the core really just trash or actually a hidden treasure of nutrients?

New Video: ICPMS-2040/2050 ProActive Rinsing
ProActive Rinsing can shorten the analysis time by sharting the rinsing sequence in advance. While measuring multiple samples, the rinsing sequence can be started early by sending the autosampler probe to rinse while collecting data using sample already in the suction line. This greatly reduces measurement time and conserves sample.

New Video: ICPMS-2040/2050 Extended Rinsing
The extended rinsing function automatically performs an additional rinse sequence when a target element exceeds a predetermined upper limit. A second rinse solution can be used in the additional rinsing sequence to improve rinsing effectiveness. Consequently, carryover is eliminated to ensure high-quality data.

Biodegradable Plastics
In order to reduce plastic waste, the development of eco-friendly alternative materials is being promoted. As an alternative, biomass plastics and biodegradable plastics are becoming more widely available. Biodegradable Plastics are plastics that are decomposed into low-molecular compounds by microorganisms in the environment. So they break down easily in nature, which is an opposite characteristic of petroleum-based plastics.
