A Case for Laboratory Automation

Problem: While laboratory instruments have become faster and more automated to increase productivity, sample preparation has continued to remain a bottleneck and source of variability for most labs. The complexity and variety of samples that typically pass through labs makes this area one of the most difficult to automate. The use of Automated sample Preparation equipment can impact:

Productivity: Automated sample preparation can save ½ hour or more of analyst time per shift which translates to ≈ 550 hours labor savings per year (0.5 hrs per shift x 3 shifts per day x 365 days per year).

Precision of automated sample preparation exceeds the precision achieved by multiple analysts across shifts which improves the quality and reliability of results. The repetitive nature of automation is more consistent than manual preparation which reduces the risk of analyst errors. This in turn lowers laboratory costs by reducing rework and lowers the risk of price concessions for offspec product due to lab error for the client.

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Shimadzu SSI GC-2014 - ARA
My research is about the capability of associative N2-fixing bacteria to fix nitrogen and it will be observed by acetylene reduction assay. My laboratory has 3 column (Restex serial no. 935315, 937846, 939370).
1. Of the three column, which is suitable for the assay?
2. How to set up the GC for ARA, especially temperature (column, detector), flow rate (carrier gas), etc.  Thank you. Respond to this member.

O'ryan Fiberoptic light source (Microscopy Questions and Answers forum)
Need specs for the transformer in an O'Ryan LS-150 fiberoptic light source. The transformer in this unit has burned out - there are no identification markings on the transformer. Advise this member.

Eppendorf 5417c braking circuit malfunction
Hi guys, I have two 5417C benchtop c'fuges that are burning-up their brake resistors just sitting ON at idle.  I have replaced the main filter caps & several small transistors and such on the main PCB, but the symptom persists.  
Has anyone dealt with this issue?  The original resistors were blown-up and a couple of PCB traces were cooked and needed bypassing as well.  I'm at my limits without schematics, and Eppendorf says there are none because they don't do component-level repairs.  $2100 for a new board seems a bit steep to me. Provide feedback.
