When would you use standardless FP corrections?

Using standardless Fundamental Parameter corrections is about getting a quick, quantitative-looking estimate without using calibration standards. These corrections model the physics of X-ray generation and interaction in the sample—how elements emit X-rays, how the sample’s matrix absorbs or enhances those X-rays, and how the instrument and detector respond. Because you aren’t calibrating against known reference materials, you rely on assumed sample properties and generic parameters, so the results come with higher uncertainties and usually lower accuracy than standard-based methods that use certified standards. This approach is ideal for rapid screening or when standards aren’t available or practical to obtain. It gives you a fast indication of which elements are present and roughly at what levels, without the time and effort needed to prepare or source standards. It’s not primarily a method for energy-scale calibration, and while it can be applied to various sample types, the trade-off is accuracy compared with standard-based corrections.
