Standard Curve



tandard Curve is presented as the easiest way in laboratory to graph calibration curve from response readings of standard solutions and identify concentrations of unknown samples. It is the best way to generate professional batch report.

There is no need to use MS Excel to graph calibration curve any more and make all calculations and other pain full process. With Standard Curve all calculation process become easy, clean and accurate. Moreover, Standard Curve calculate method detection limit (MDL) compliant with international standard (ISO-11843-2 and Hubaux & Vos method).

Standard Curve is robust industrial productivity software. It has been developed in real laboratory research world. In addition, all data will be saved in local computer database and it can be backed up at anytime.

Calibration curve is at the heart of chemical analysis. It is defined as the process by which the response of an instrument (in metrology called "indication of the measuring instrument") is related to the value of the concentration of the analyte. A typical example in analytical chemistry is the calibration of a GC (gas chromatography) analysis. The heights of GC peaks are measured as a function of the concentration of the analyte in a series of standard solutions ("calibration solutions") and a linear equation fitted to the data.

Based on the principles of calibration curve, the idea of Standard Curve has been developed over the past ten years to cover the needs in laboratory analysis.
