Exploring the Unknown, From a Grain‘dust’Start now

In this era of rapid technological advancement, in-depth analysis of the cleanliness of automotive components is being increasingly valued by more and more companies. To achieve a transition from 'quantity' to 'quality'. We are on our way .....

From the types, sizes, and quantities of particulate matter that have been of concern in the past, （Particle Types in Standard Analysis -4）. Current elemental analysis and hardness. It can be seen that everyone has updated and higher requirements in the field of cleanliness.

in the latestVDA19.1andISO16232In the standards, it is mentioned to conduct in-depth analysis, such asSEM / EDX，LIBS， Raman spectroscopy, infrared spectroscopy (IR), X-ray analysis, and so on.

According to the standards we have learned, based on the customer's needs, the current main approach is to utilizeSEM / EDXConduct in-depth analysis. In this test, it is necessary to define the type of the detected element and its percentage. Refer to the following figure:

Apart from thisCustomer concernsOther elements include:

Some cleanliness standards not only involve material composition, but also classify the hardness values of particulate matter.
