There are 2 kinds of methods.

1 Destructive ones (auto titration, spectroscope) mean the samples will be destroyed while testing. They create more accurate results but take longer time and more costs.

2 Non-destructive (x-ray, ultrasound) means the samples will be unharmed. It is not expensive and fast but generates less accurate results.
