We will be implementing NuclearIQ soon and I was wondering if it has QC capabilities for Chemistry benchtop instrumentation. Our old system (WINCDMS) provided both data and QC capabilities. I have heard that some plants using NuclearIQ incorporate LabStats for their benchtop QC program. Any information would be appreciated.
Yes, NuclearIQ® has QC functionality built into the application that allows the User to define a Quality Control instrument and then control the input of sample results based on the results of the QC checks that are performed on that instrument.
For Bench Top Instruments, NuclearIQ® employs the RSD method.
- 1. Relative Standard Deviation Method (RSD) – The application uses the Industry accepted ± 3 Standard Deviation around the Mean. This method will place an instrument Out-of-Control when a QC check in outside 3 Standard Deviation OR if there are 2 consecutive points outside 2 Standard Deviations. In addition, the standard warnings of 7 consecutive point in an upward to downward trend and 15 points on one side of the mean also apply.
The QC Module within NuclearIQ® allows the User to set Pre-Analysis QC, Post-Analysis QC OR both Pre-Analysis and Post-Analysis QC checks. Each QC check has an allowable window defined as well. So if a Reactor Boron analysis requires a Pre-QC and a Post-QC, the User can define the acceptance window as within 60 minutes of the Sample Analysis. This ensures that the QC checks are relative for the results that are generated.
In addition, within Version 22.214.171.124 there is new functionality added to the QC module.
- 1. Multiple QC instruments can be assigned to an analysis. So, if there are multiple Ion Chromatograph instruments that can be used to perform an analysis, the User can select the instrument used and tie the sample analysis results to a specific instrument. This allows Users to trend the behavior of the results produced by each instrument. Since each data point holds its’ specific QC information, this also allows for detailed auditing of chemistry data in the future.
- 2. Instrument Logbook. This functionality allows the User to keep a detailed Logbook of each instrument. The Logbook houses extensive records for each instrument, such as Calibration records, Calibration History, Current Calibration Status, Maintenance Log Entries, Method development packages, Instrument User’s manual, Consumable Parts List, and Out-of-Service times.
- 3. Instrument In-Service/Out-of-Service capabilities. The Instrument Log book allows the User to control In-Service/Out-of-Service status of instruments by verifying the Calibration is current and the QC checks have been performed. When a sample result is entered into a system in NuclearIQ®, the instrument logbook checks the calibration records to ensure the instrument is calibrated. If the Instrument is Calibrated and In-Service, the QC Module then enforces the QC check requirements (i.e. Control performed within the allowed window, QC check meets RSD Method requirements). If all requirements are met, the results are then stored in the database.
The settings in the QC module and Instrument Logbook are User definable so that the Users can tailor the application to their specific needs.
With all of this being said, NuclearIQ® also allows User’s to interface with Labstats, and have Labstats perform the evaluation and pass the final determination back to NuclearIQ®. The Instrument Logbook book functionality can be used with Labstat results as well. So, Users can use Labstat’s or NuclearIQ® and have the same functionality.
NuclearIQ® displays one of the three following error messages:
- “Object reference not set to an instance of an object”
- “Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index”
- “Object cannot be cast from DBNull to other types”
The error messages above indicate that there may be a problem with the database or an issue with the code. The user will need to contact GCR for further assistance and will need to provide the following information: version of NuclearIQ® being run and operation attempted to be performed at the time of error.
The NuclearIQ® application displays an “A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 – The specified network name is no longer available.)” error.
This error occurs when the application loses connection with the database temporarily.
The NuclearIQ® application displays a “Could not load file or assembly ‘Gigasoft.ProEssentials, Version=2.0.3200.19159, Culture=neutral, PublicKeyToken=38150f10c0d12be5’ or one of its dependencies. An attempt was made to load a program with an incorrect format.” error.
This error appears when you run the wrong version of code for the operating system of the machine you are using.
The NuclearIQ® application displays a “Report file location is invalid” error while attempting to access the report module, print a report or print an active schedule.
This message indicates that you either a) cannot find the report file that is to be used to print the schedule based upon your sort option or b) cannot access the location set in the options for the Report File Directory.
