QC Calculator
Can be used with initial replication data from a control material
to calculate the mean, SD, CV, and control limits. Can also be
used to calculate cumulative mean, SD, CV, and control limits
when user enters summation terms from earlier calculations. Prepares
a blank control chart that can be printed.
QC Plotter
Can be used to display control results on a control chart. User
enters the mean and SD for a control material (available from
QC Calculator), specifies the control limits to be drawn on the
chart, and enters up to 60 control results to be plotted on the
control chart that can be printed.
QC
Simulator
Can be used to prepare trial sets of data that demonstrate the
effects of systematic errors (shift of mean) and random errors
(increase in SD). User can display these trial sets of data in
the form of histograms and can also view these data on a control
chart whose limits represent the stable mean and SD of a method.
Useful to learn how different analytical errors affect the control
results.
QC Trainer
Can be used to generate simulated data that can be used to practice
the interpretation of different control rules, such as 13s,
12s, and 13s/22s/R4s
with N=2, 13s, 12s, and 13s/22s/R4s
with N=3, and 13s, 12s, and 13s/22s/R4s/41s
with N=4. User can select the number of control measurements
per run (N/run) and the control rules to be applied, display
control results for the next run, interpret that data to judge
the control status, and have the program verify the correctness
of that interpretation. Useful to train analysts to properly
interpret control data using specific control rules
QC Checker
Can be used to manually enter control values for display on a
control chart and for checking control status by selected control
rules. The user enters the values for one run, checks control
status, then enters the values for the next run, etc. Assists
the user in checking specific sets of control data and for clarifying
the interpretation of the control results. |
