“To PM or not to PM, that is the question.”
With sincere apologies to The Bard, this is a quandry that is often faced by many lab managers when their facilities group or a vendor informs them that a preventive maintenance procedure is being scheduled.
How do you know when the time is right to actually do such work (spend money)? Just because the manufacturer recommends that a PM be done every 6 or 12 months, is that the right thing to do? What if the instrument rarely gets used?
All too often, lab managers or those whose budgets will be tapped for PM services are in the position of ‘erring on the side of caution’ or take a break/fix approach. Spending unnecessarily is obviously not desirable, however waiting till something breaks can cost dearly. There has to be a better way.
A number of common lab instruments have PC based controllers (liquid handlers, readers, integrated systems) and many of those instruments include ‘log files’, which are used by operators to troubleshoot assays or techs to repair instruments. Savvy lab managers and OEM’s can use these logs to track actual usage as opposed to just following suggested time intervals. It requires someone to actually look up the log files (if they exist) and be able to interpret the data but unfortunately there are not a lot of alternatives.
The LabSquad (caution: gratuitous self promotion ahead) is looking for off-the-shelf monitoring solutions that can be adapted to lab use. Other industries commonly use data logging equipment to monitor temperature or humidity but machine usage (especially outside of manufacturing environments) is relatively uncommon. Additional obstacles present themselves in that not all lab instruments use a PC controller and there are not a lot of inexpensive data loggers to choose from. Not to be deterred, we are also looking at custom developed solutions that could be added to any lab instrument which would monitor usage and be inexpensive (cost less than US$100). Just to make it interesting, we would like such devices to wirelessly communicate with a host PC or tablet such that someone could simply pass by a lab like the fellow who reads your home water meter does by driving by your house to assess the usage of key instruments.
While The LabSquad makes it’s living by performing PM’s and repairs, we do strongly believe that we can help labs better spend their support budgets by investing available support funding more wisely. Some instruments (the workhorses) might need more frequent attention, while lesser used devices might have their PM’s pushed out further.
As Paloneus says in Hamlet, Act 2 Scene 2; “Though this be madness, yet there is method in it.” Let us know what you think about PM scheduling and how your lab goes about keeping your instruments ‘research ready.’
