Sample Bar Coding?
Anyone help me out with the following questions? Thanks!
Do you have a bar-coding system for tracking samples that you are happy with?
If yes, do you use it for:
Does it meet chain of custody requirements for in lab sample control?
Is it a stand alone system? If yes, who is the manufacturer?
Is it integrated into a LIMS system? If yes, who is the manufacturer?
Sorry this posting is so late.
We use barcoding for COC and for entering info into our instruments. The capability came with our LIMS: Element by Promium (Bothel, WA).
When we upgraded our LIMS, we made a concerted effort to move away from paper and hand-entered data, from log-in info to results. The bar coding was a natural part of this effort.
We found, though, that you have to be fairly careful with the type of bar code reader you buy. They are made to read at various distances. We had to try a couple of models before we found the type that worked best for us. Our codes are one-dimensional, that is they're really just a set of bars, not a 2D "speckle."
And we've been very pleased with performance, efficiency gains, and reduction in hand-entry errors.
Added later: I forgot to add that we use bar coding on all sample labels, too. The labels are printed out at sample log-in, and the analysts read the codes off the labels at the instruments.

We went with the WASP WL S9500. Reasons: (1) good compromise between sensitivity and readable distance; (2) uses a cord (we found the rechargeable battery readers to go dead too often); (3) good service from the company; (4) reasonable cost.
