4.3.43 If/if not methodThis method is used to perform a comparison test between a “sample curve” and a“reference curve”. The test can be based on any calculation available, integrationor peak coordinates. The test will direct VoltaMaster 4 to continue in one directionor the other depending upon the result of this comparison. You can compare, forexample, 2 cycles within one cyclic voltammetry to look for stability of the potentialpeak value or compare an experimental curve to another curve from a method ofthe same sequence or stored on your computer as a curve. If/if not is available invirtual mode with every VoltaLab system, in real mode with VoltaLab 10, VoltaLab21, VoltaLab 40 VoltaLab 50 and VoltaLab 80.Consult the Help file, keyword index: If/if not method - Method editing.4.3.44 Jump to methodThis method is placed in a sequence to force VoltaMaster 4 to jump to a specifiedmethod of the sequence. The Jump to method is often used in combination withthe If/if not method to build “conditional loops”.Consult the Help file, keyword index: Jump to method - Method editing.4.3.45 Standard additionThis method calculates the concentration taking into account dilution volumes andhandling up to four standard additions plus the blank subtraction. The signal canbe a peak integration (Total, positive or negative I or dI) or a peak coordinate inpotential, differential potential, charge, current, differential current or A/D IN withselectable potential, time or current windows. Standard addition is a commonprotocol to determine low concentrations. The principle is to run a blank, add thesample of unknown concentration to this blank and run it, then add three times in arow a given small volume of a standard solution of well known concentration. Thencalculation provides the concentration in the sample, assuming that the recordedsignal is linearly proportional to the concentration and handling volumes.Consult the Help file, keyword index: Standard addition - Method editing.60VoltaMaster 4 - Version 7.0xSection 4, Chapter 3: Methods available
4.3.46 Standard calibrationThis method calculates the concentration taking in account dilution volumesand handling up to 4 calibration curves (independent setting for their respectiveconcentrations) plus a blank subtraction. The signals can be a peak integration(Total, positive or negative I or dI) or a peak coordinate in potential, differentialpotential, charge, current, differential current or A/D IN with selectable potential,time or current windows. Standard calibration is a common protocol to determinemedium concentrations. The principle is to run a set of standard solutions ofwell known concentration and then to run the sample of unknown concentration.Interpolation provides the concentration in the sample, assuming that the recordedsignal is proportional to the concentration and handling dilution volumes if needed.Linear, as well as logarithmic or exponential relationships are handled.Consult the Help file, keyword index: Standard calibration - Method editing.VoltaMaster 4 - Version 7.0x 61Section 4, Chapter 3: Methods available
