- All samples will be screened for U and excess Th prior to isotope dilution and extraction chromatography processes for purification and measurement. Only samples with acceptable ranges of Th will be selected for analysis. If a sample is considered not suitable for analysis, the client will only be charged for the screening.
- Samples that did not remain closed with respect to U and Th isotopes will yield ages that may not fit in with established chronologies.
- We utilize an analytical method which provides precise measurement of 233U-234U-235U-236U-238U-229Th-230Th-232Th with high resolution whether a sample remained closed with respect to U and Th or displays open system behavior.
Please consult the lab before submitting samples.
