Just looking towards those who like us use ALS for their water sampling?
Have you noticed that the lowest level they now sample down to is only 14ug/l which is not low enough for the RA guidelines of 10ug/l?
A quote from ALS:
"The results are <14.4ug/l, which is the new reporting limit for this test, meaning that we are unable to give you a result below <14.4ug/l.
Our Limits of Detection have been replaced with Limits of Quantification. Communications regarding this change were issued in December; COM 116/19 on the 9th December, and COM 120/19 on the 16th December."
