Hydrofluoric acid matrix The HF substrate must have a hydrofluoric acid resistant system, but due to insufficient funding, the atomizer must be made of PFA. Hydrofluoric acid resistant systems often

Microwave digestion generally uses nitric acid to stabilize the elements in the solution, and the concentration is slightly higher. For beginners, this conclusion is very useful. However, several issu

Hydrofluoric acid matrix HF matrixA hydrofluoric acid-resistant system must be needed. In fact, the funding is insufficient, so the atomizer must be PFA . Hydrofluoric acid-resistant system
