Why You Should Interface Your Instruments to LIMS

CSols Information Insider: Why You Should Interface Your Instruments to LIMSIt’s always a shock when reviewing the results of LIMS surveys that ask whether the lab instruments have been interfaced with the LIMS.  One would expect that practically all LIMS implementations would have interfaced the instruments, right?  Well, it turns out that a large percentage of LIMS implementations have not interfaced the lab instruments with the system.  Why not?  The answers vary but include:

  • We plan to get to instrument interfacing in the next phase of the LIMS implementation
  • We had to get the management reports done first
  • We felt it cost too much to interface the instruments
  • We felt that cutting and pasting was good enough

All of these reasons for not interfacing the instruments to the LIMS may seem reasonable to the LIMS owners, but there are overwhelming reasons to interface every instrument in your laboratory to your LIMS that can be reasonable.  But before we get too far into this, let’s explore the types of instruments that can be interfaced with a LIMS.

Types of Instruments that can be Interfaced to LIMS

Instruments to be interfaced to a LIMS fall into three major categories:

  • Simple instruments
    These types of instruments are able to output a result but no real metadata (sampleID, testID, test parameters) to enable unassisted interfacing.  Methods of interfacing these include activating the data transfer from within the data entry screen of the LIMS or utilizing an intermediary interfacing software package where the needed metadata can be associated with the result.  Interestingly, these “simple instruments” are sometimes the most challenging to interface to the LIMS
  • Uni-directional instruments
    These types of instruments are able to output a data report and results file but do not have a facility to import information. Within the output files, the metadata needed to allow unassisted interfacing will be available.  Interfacing these instruments is done by the LIMS or interfacing software picking up the file in a location and then parsing and entering the information/results into the LIMS.  Additionally, many instrument interfacing systems will offer a large variety of drivers for interfacing these types of instruments and some vendors will even create new drivers, if requested.
  • Bi-directional instruments
    These types of instruments are able to both output data reports and results files and have an Application Programming Interface (API) to enable the import of data, information, protocols, worklists, commands/function calls, etc. These sophisticated instrument systems, like many chromatography data systems and robotic systems, are interfaced with the LIMS programmatically.  Many LIMS companies will offer sophisticated bi-directional interfaces to the most popular instrument systems in this class.  If an application is not commercially available, a full featured interface can be programmatically created.

Why Instrument Interfacing With LIMS Is Helpful

There are a number of reasons why it is beneficial to interface the lab instruments to LIMS.  Some of the most prevalent benefits of instrument integration are discussed below.

Reason #1: Increase Productivity/Effectiveness

One of the best reasons to interface your instruments to your LIMS is the increase in lab productivity and scientist effectiveness it yields.  Removing the manual entering of data, or even the cutting and pasting of data from the instrument to the LIMS saves a ton of time and effort.

Likewise, if a bi-directional interface is being utilized, you will also eliminate the time required to enter the run information, parameters, etc. into the instrument system.  This can all be set up in your LIMS and then transferred over electronically to the instrument.  Increasing productivity and sample throughput are key goals in all quality control and testing labs.  Increasing effectiveness (i.e. increasing the amount of time available for a scientist to do science) is a key goal in research labs.

Reason #2: Increase Data Quality/Data Integrity

Another key reason to interface your instruments to your LIMS is the increase in data quality and integrity that it yields.  By removing the “human element” from the data transfer and entry equation, a huge source of error is removed.

Removing transcription errors will significantly increase the quality of your data.  A very large issue in laboratories that are coming under increased scrutiny in FDA regulated labs is data integrity.  How the data is captured and recorded from the source (i.e. instrument) to the data system (LIMS or ELN) is a major source of warning letters.  Instrument integration with your LIMS or ELN will greatly reduce the impact of this issue.

Reason #3: Increase User Satisfaction and LIMS Adoption

One of the complaints often heard by the scientists in the lab when a LIMS is implemented is that there was not much in the LIMS that helped them with their job.  In fact, they will sometimes complain that the LIMS has made more work for them and that they “Hate LIMS”.  One of the best ways to increase the scientists’ LIMS satisfaction is to interface the lab instruments to the LIMS.

Have you interfaced your lab instruments with your LIMS?  If not, why not?  If you have, are you using the instrument interfacing facility from your LIMS or another software system?  What types of interfaces are you running?  Simple? Uni-directional? Bi-directional?

    Great advice for all.

  2. Gary Croft says:

    Ive spent many years building programs to convert the data off lab equipment so that Lims systems can import the data as the big problem is there is no standardisation in equipment manufacturers there are like 3 or 4 big names in the LIMS market and ive yet to see any standard data files from the equipment manufacturers its time for them to unite in a standard export file so that the process can be simplified, that way LIMS systems can have a standard loading module coded in for data integration.

  3. Heimen van Lagen says:

    We try to interface every instrument when possible. From simple balances to ICP, HPLC and GC.
    As well uni as bi-directional. We use partial the interface module of the LIMS itsselve (Labstation from Labware). We wrote a lot of interfaces ourselve for the Chromatography data systems such as Chromeleon.
    We act international and we try to have the same instruments worldwide, so we can use the same logic everywhere.

    Indeed th benefits are that it is saving a lot of time and improvement of Quality
