What is the unit in GC peak area?

However it is measured, the units of peak area are the product of the x and y units. Thus, in a chromatogram where the x is time in minutes and y is volts, the area is in volts-minute. In absorption spectrum where the x is nm (nanometers) and y is absorbance, the area has the units of absorbance-nm.

How is peak area measured?

Peak area calculation. A peak consists of a number of counts in adjacent channels. In principle, therefore, measurement of peak area is simply the summation of a number of channel contents over all channels within the peak, G. Subtract the underlying continuum, B to create a net area count (A) instead of the gross area ...

How do you find peak area in GCMS?

The area of each peak can be found by using one of the following methods: * The peak can be treated as a triangle and the formula, Area = height x width at 1/2 height x attenuation can be applied.

What does area mean in GC MS?

Typically, the y-axis, or the area of the peak, is a reflection of the amount of a specific analyte that's present. When looking at a GC/MS chromatogram, the area will be based on the number of counts taken by the mass spectrometer detector at the point of retention.
