A calibration series of a mixed benzoxazinoid standard, run by HPLC with an
'Agilent' diode array detector (G1315A), as ten 'ChemStation' .D
directories in extdata. Find them with
system.file("extdata", "benzoxazinoid_standards", package = "chromConverter").
Details
BENZOS_1000PPM.DtoBENZOS_4PPM.D: nine twofold dilutions from 1000 ppm, injected between 20 and 22 June 2023. The names round the last three, which are 15.625, 7.8125 and 3.90625 ppm.MEOH.D: a methanol blank, run with the same method on 15 June 2023.
Each directory holds the 254 nm trace (dad1A.ch) and the 'ChemStation'
report (Report.TXT). BENZOS_250PPM.D also holds the traces at 230, 320,
360 and 210 nm (dad1B.ch to dad1E.ch), and the pump's pressure, flow
and solvent composition through the run (LCDIAG.REG), which
read_agilent_d returns with what = "instrument".
The standard gives four peaks at 254 nm, eluting in the 250 ppm run at 12.5 (DIBOA), 19.1 (DIMBOA), 21.0 (BOA) and 28.2 minutes (MBOA).
