About This Item
ASTM C1845 is the ASTM standard that describes a practice for separating lanthanide elements from uranium matrices using high pressure ion chromatography (HPIC) for isotopic analyses by inductively coupled plasma mass spectrometry (ICP-MS). It provides a focused technical approach for preparing samples before measurement, helping support more consistent analytical results. For laboratories working with uranium-containing materials and lanthanide separations, this standard can be an important reference for controlled sample preparation and traceable testing workflows.
ASTM C1845 standard overview
The ASTM C1845 standard addresses a specialized separation practice designed for lanthanide elements in uranium matrices, with the separated fractions intended for isotopic analysis by ICP-MS. Its main value is in defining a consistent laboratory approach for sample preparation ahead of instrumental measurement. By using high pressure ion chromatography, the practice supports a more structured separation step, which can help reduce analytical variability and improve confidence in downstream isotopic results.
Where is ASTM C1845 used?
This standard is typically used in analytical laboratories that handle uranium-bearing samples and need to isolate lanthanide elements before ICP-MS testing. It is relevant in workflows where sample cleanup, matrix separation, and isotope measurement must be carefully controlled. ASTM C1845 may also be used by labs performing method development, quality checks, or routine testing involving chromatography systems and mass spectrometry instruments in nuclear or radiochemical analysis settings.
Practical importance of ASTM C1845
ASTM C1845 helps laboratories use a common practice for a separation step that can directly affect the reliability of isotopic analyses. In practice, that matters for consistency, method comparison, and quality control when working with complex uranium matrices. The standard can also support procurement and compliance decisions by giving organizations a recognized technical reference for separation and sample preparation before ICP-MS measurement. For many users, that reduces uncertainty in laboratory procedures.
