Hey, when assigning labels to my sample set i usually go as follows:

S0101 Standard 1
U0101 Batch X prep 1
U0102 Batch X Prep 2
S0201 Standard 2
clear cal
cal S01* S02*
quant U01*

All the unknowns have duplicate injections.
My question is; if i want to run say 6 different samples between these standards that are NOT the same batch, should each have a unique label and then it will be easier to average injections? (U01, 02, 03 etc.)

I'm just wondering what is best practise to make the software more versatile down the line (calculations and reporting).

Thanks guys! Look forward to a reply.

Oops, thanks, wrong spot

We made a sample custom field to fill in Batch.
Then we group our tables in our report by batch.
This way we can make averages, min, max, stdev, ... within the batch in an easy way (at least for us).

Do you do bracketing standards?

If so, have you figured out a good way to have one report per run?

I'm looking to have one report that shows system suit, blanks, then first 2 standards averaged, then first sample, then next 2 standards, etc.

So far I have it set up that it can report with only the first two standards and whatever they bracket in the sample set. I can't figure out a way to have one report that works for any sample set size. There doesn't seem to be a data filter for the number of injections. (With all standards labelled S*, there's no way to tell it only use S01 and S02 for this page and then S02 S03 for the next one and so on). Admittedly I haven't had enough time to sit and just figure out this problem itself. And it would help if I got sent to the training for custom fields and reports instead of the advanced processing/sample set up training which I already knew.

When I called Waters the lady suggested I'd have to have a page for each set of standards that filters for specific labels. But I imagine there's a way around this...this software is pretty advanced, there's gotta be a way

we write, copy, paste edit consecutive tables for batches of samples. We change the order/filter options for each one thuse getting only the set desired.

I don't understand what you mean
