let isotherm = IsothermAnalysis.fromIGA(file);

API Documentation

Development guidelines

• there are two data types Adsorption Isotherm and Desorption Isotherm. Ideally, this is directly provided in the file and we parse it from there. Otherwise, if the pressure is descending, it is desorption.
• the jcamp has the following fields:

field	meaning	typical unit
x	absolute pressure	kPa
p	relative pressure (pressure relative to staturation pressure)	unitless
y	gravimetric excess uptake	mmol/g

If available, we try to use the following fields for metadata:

• sampleWeight: For example, 1.
• sampleWeightUnit: For example, g.
• adsorptive: For example, N2.
