Sorry Hiroshi,

ADAMS is the author of the book: Identification of Essential Oil Components by Gas Chromatography/mass Spectrometry.

I have seen higher RI (ref) in MS-DIAL than in others platform like this one: https://webbook.nist.gov/chemistry/.

Hi Hiroshi.
Thank you for help me.

I have been using alkanes mix for identification of compounds. Why the RI values (reference) for the file 'all records with Kovats RI' are higher than ADAMS records?

Example: Limonene MS-DIAL: RI (ref) 1233
                              ADAMS: RI (ref) 1029.5

MS-DIAL / GC-MS and MS-DIAL
I have been using a mass spectrometer Shimadzu GCMS-QP2010MS-DIAL for GC-MS-based untargeted metabolomics.
I have two questions about processing by MS-DIAL:
- For compounds identification, what is the best MSP file?
- What "RI tolerance" should I use?
