Data Quality

To maintain high data quality, instrument performance is routinely monitored using one or more secondary standards.

We also regularly participate in interlaboratory exercises. This includes G-probe (most recently G-probe 8 in November 2011) and the recent INTAV intercomparison of tephrochronology laboratories (Kuehn et al., 2011 - see lab 28).
These provide a source of external quality control.
