Rationale

Listing the chemicals in the scope is an odd choice. I would move this to summary (section 4) Negative: The scope should list the type of MS described. Is it EI? CI? TOF? The description in 1.4 seems very instrument specific, which is fine, but then the type of instrument needs to be declared. Table 1 AR, ARF, ARRF are not defined. should be in a footnote Table 5 SBP is a trade name. It should be Bonded; poly(dimethyl siloxane) phase 13 While there is a precision and bias statement, I think some of the data should be presented and not in a report that is not searchable via google.
