uality Control Chart is a powerful statistical process control software (SPC). It is used to graph quality control charts in order to monitor and control a process. Monitoring and controlling the process ensures that it operates at its full potential. At its full potential, the process can make as much conforming product as possible with a minimum (if not an elimination) of waste.
Quality Control Chart used in chemical laboratory or factory to graph quality control and process capability charts as performance-based program. It can be used to graph hundreds of QC charts and perform automatic calculations of control limits.
Use Quality Control Chart tp help you:
Quality Control Chart is database software which runs on multiple PCs and interacts with users. All data stored into single database where it can be accessed from anywhere. Several types of databases are supported such as (MS Access, MS SQL and MySQL).
As an example of the QC chart for a quality control in testing laboratories, we will take Laboratory Control Sample (QC) for selective test (Total Organic Carbons). QC sample is a real sample contains known concentration of the analyte, the QC sample processed along with all other samples in one batch. Every batch of 20 real samples contains one QC sample. Final result from all QC samples were collected and graph using Quality Control Chart software. Below is an example of statistical interpretations of all QC results.
Quality Control Chart automatically calculate QC limits which include:
When QC results between warnning limits UWL/LWL (orange lines) considered to be PASS. If the QC result is outside action limits (red lines) i.e. above UAL or lower than LAL then batch considered to be FAIL unless there is ajustification reason (e.g. double spiked by accident is not fail). If the QC result comes in between the orange line and red line (i.e. between UAL and UWL or between LAL and LWL) the batch most likely PASS with taking serious attention to the next point. If the same result appear contiously for the next couple of bacthes without justification reason then last batch considered FAIL and the system is out of statistical control.
A. System Requirements to work with normal MS Acess Database:
Note: MS Access is not required to be installed to work with Quality Control Chart.
B. System Requirements to work MS SQL and My SQL Database (Used for multiple PCs connected to one server):
The software shipped with three database files MS Access 2000, MS SQL 2000 and MySQL 5.1. The MS Access database assigned as a default database at installation. To use MS SQL and MySQL files, an addition configurations required as per help files instructions.
Using MS SQL or MySQL, connect all lab departments and sections into one database. Help quality assurance program maintain the quality of service provided to customers.
The purpose of Quality Control Chart is to determine if a system is in statistical control. This determination is made by examining the location of individual points in relation to the warning limits (UWL,LWL) and the control limits (UCL,LCL), and the distribution of the points around the central line (Mean). If we assume that the data are normally distributed, then the probability of finding a point at any distance from the mean value can be determined from the normal distribution curve.
In any of the following cases for individual sample chart, the system will be out of control:
All above points are to help you identify the error in your system, eventually you are the decision maker, to decide if any individual is outlier or not.
Once you instal Quality Control Chart, the software will configure database automatically as MS Access database.
We recommend to start with one point and continue adding until you reach 22 points. Once you have 22 points you will get clear picture of your system if it's under statistical control or not.
Your data stored in database. The default detabase is MS Access database which by default located in C:\Program files\Chemiasoft\QC Chart\Database\qcchart_access2000_db.mdb. Make backup for this file frequently. If you are using MS SQL or MySQL databases then you need help from an IT person who can make backup from the server where the database is located.
Yes, for sure. First you must decide which type of database you want and how many computer want access. Quality Control Chart support three database types (MS Access, MS SQL and MySQL), you may need IT person to answer this question. Database will be installed in server, clients computer will access the database through Quality Control Chart installed on each computer. After that you have to order one licesne for each computer. If you need any futher help please contact us..
It depends on you. If you are using only one PC to access the data then downloaded version is enough. If more than one PC then it's better to get delivery version with USB dongle so you can use Quality Control Chart on any PC you want once you connect the USB dongle.
