Equipment
In the form of so-called equipment drivers QCX/Laboratory offers automatic equipment control and/or data acquisition for a wide range of analytical instruments:
XRF X-ray Fluorescence Spectrometers
XRD X-ray Diffractometers
PSZ Particle Size Analyzers
BLN Specific Surface Analyzers (Blaine)
OES Optical Emission Spectrometers (Spark or ICP)
CSH Carbon/Sulphur/Hydrogen Combustion Analyzers
COL Colour Analyzers
CST Cement Strength Testing equipment
. . . and many more
Equipment units such as crushers, mills and presses for X-ray powder sample preparation can also - pending the specifications for the individual units - be interfaced from QCX/Laboratory. Today, most newer analysis instruments are interfaced via a dedicated PC, but the link may be direct. One example of interfacing via PC's is for XRF spectrometers: This communication set-up implies that procedures for calibration, monitor analysis, stability tests etc and special instrument checks (and remote service) are performed from the X-ray suppliers application software package (e.g. "WinXRF", "SuperQ", "XPertIndustry", "X.40", "Spectraplus ", "XPertEase"). In this typical set-up the QCX system transfers relevant sample ID & analysis parameters during analysis start-up and later picks up the calculated analysis upon completion of the analysis sequence.
Data Acceptance
Careful screening of automatically generated data before eventually being passed on for on-line process control applications is vital for the control performance. The basic standard facilities of QCX/Laboratory include extensive data acceptance and data validation options designed to work under any degree of automation. Up to 4 data limit checks are applied:
It can be defined which actions are to be taken if a violation is detected; as an example for a violation situation it could be defined to register the value but not pass it on for a relevant control application, or an alarm calling for operator attention could be generated. Data approval, validation or editing is supported in accordance with the implemented user access control facilities. Thus, normally only authorized personnel can access these priority functions, and it will be reported "who did what at which time". But, if so desired the system can be configured to disable all protection and "tell tale" facilities.
