In pipeline industry,direct reading spectrometer is widely used to identify the materials.But except for the PMI,chemical analysis method is also often used.Then what is the advantages and disadvantages of chemical analysis method?

Advantages of chemical analysis method for positive materials:

High Accuracy:The chemical analysis methodis an arbitration analysis method used by national laboratories with high accuracy; the interference between elements can be shielded with chemical reagents, so that the elements do not interfere with each other, and the curve can be non-linear regression to ensure detection accuracy;

The result of chemical analysis methodis more representative:the sampling process is in-depth sample center and multi-point collection,especially for uneven samples and samples after surface treatment, which can be accurately detected; wide application fields, small limitations, and standard curve can be established. For determination, the steel material element analysis analyzer instrument can perform curve self-test.

The purchase and maintenance cost of chemical analysis equipment is low, and the maintenance is relatively simple.

Disadvantages of chemical analysis method for positive materials:

The process of chemical analysis methodis more complex than PMI, and the workload is larger.

Chemical analysis methodis not suitable for rapid analysis before furnace.

The test sample will be destroyed due to the sampling processof chemical analysis method.
