Run number

One question of chief interest concerns the number of runs that can be run with one individual SEC column. The lifetime of the sorbent itself must be tested as well as the maximum run number for the packed column. Because column packing procedures for SEC columns are rather time-consuming and all SEC columns have to be checked very carefully with respect to performance, very frequent repacking of the column is unreasonable. Therefore, CIP protocols are generally necessary. The CIP protocol should be developed as part of the process validation program.

Analysis of the chromatogram is carried out Interactively with the operator directing the flow of analysis from the computer keyboard, or in the automatic mode immediately after data collection to an extent specified using SETUP. Automatic analysis may also be applied to a series of chromatograms at any time by putting the run numbers or names of the files in the run number file. Before the next set of data collections, the programs check that the number in the run number file is the latest run number for all the files on the disk.

Produce a post-mortem plot using data stored by means of a PREPARE statement. 1, 3, 4 are the run numbers. If the run list is omitted, all runs are plotted. X, Z etc., are the vertical variables. The last four parameters specify axis scaling and are optional, i.e., GRAPH X,Y,Z plots all runs with automatic scaling. 

Unsubscripted variable expected or positive run number in GRAPH or TGRAPH or syntax error in output or declaration = expected. 

A data collection task updates the run database by associating a run number with the entry for the task and by setting the completion status in the entry. The run number is also used to assign a name to the data file created by the data collection task, thus guaranteeing that each data file has unique name. 

We provide a query capability for the run database so that the user can review his task assignments and list the run numbers that are associated with the data files created by the data collection task. 

At the present time the only online facility that we provide for analyzing the data is the display function, which provides graphical outputs tailored to the data in the diffraction data files. The user specifies the run number for the data he wishes to plot. The display program then loads the header from the appropriate data file and determines what kind of plot to display. The user can dump the resulting plot to the printer to provide a record of his experiment. The "revise file" function can be used to create auxiliary files for plotting selected features of the data. 

A copolymer of butadiene and styrene is known as poly (butadiene-costyrene). A copolymer obtained from two monomers is a bipolymer, a copolymer from three monomers is a terpolymer and so on. Run numbers R is defined as average number of monomer sequences in 100 monomer units. In a bipolymer from monomers M and M2, fraction [M1]/[M2] in the copolymer formed is denoted by f and fraction...

Another simpler criterion is that of Wilhelm and Kwauk (Kwauk and Liu, 2000), which is based solely on the P rUn number-if it is lower than 0.13, particulate fluidization exists and if it is higher than 1.3, bubbling fluidization exists. 

Precision data can be documented in bar charts or control charts such as Shewhart control charts (see the discussion of internal quality control in Section 8.2.3.5). Bar charts plot %RSD values with their corresponding confidence interval. Control charts plot the individual measurement results and the means of sets of measurements with their confidence level (or with horizontal lines representing limits, see below) as a function of the measurement number and the run number, respectively [15,55,56, 58,72, 85]. 

Two aspects are important for IQC (1) the analysis of control materials such as reference materials or spiked samples to monitor trueness and (2) replication of analysis to monitor precision. Of high value in IQC are also blank samples and blind samples. Both IQC aspects form a part of statistical control, a tool for monitoring the accuracy of an analytical system. In a control chart, such as a Shewhart control chart, measured values of repeated analyses of a reference material are plotted against the run number. Based on the data in a control chart, a method is defined either as an analytical system under control or as an analytical system out of control. This interpretation is possible by drawing horizontal lines on the chart x(mean value), x + s (SD) and x - s, x + 2s (upper warning limit) and x-2s (lower warning limit), and x + 3s (upper action or control limit) and x- 3s (lower action or control limit). An analytical system is under control if no more than 5% of the measured values exceed the warning limits [2,6, 85].
