The name of the file format is netCDF, with home page:

  http://www.unidata.ucar.edu/packages/netcdf/

A precise description of the netCDF format is here:

  http://www.unidata.ucar.edu/packages/netcdf/guidec/guidec-18.html#HEADING18-0

We don't have any chromatography-related software, but there is some
ANDI-related software and documentation at:

 ftp://ftp.sjo.appliedbiosystems.com/pub/andi-MS/

I also found this note in our email support archives at

 http://www.unidata.ucar.edu/cgi-bin/mfs/70/4056

   We develop and maintain netCDF, but the use of netCDF in analytical
   chemistry is an independent effort (in other words, we know very
   little about the ANDI chromatography standard).  We know about the
   article "STANDARDS FOR CHROMATOGRAPHY DATA SYSTEMS: ASTM adopts
   protocols for analytical data interchange (Andi)" at

     http://pubs.acs.org/hotartcl/tcaw/98/may/stan.html

   The resulting standard specification and guide may be downloaded
   from ASTM:

   E1947-98 Standard Specification for Analytical Data Interchange
   Protocol for Chromatographic Data

   E1948-98 Standard Guide for Analytical Data Interchange Protocol for
   Chromatographic Data

   You can also type in the keywords "analytical" or "spectroscopy" in
   the netCDF support email archive search box near the bottom of the
   netCDF web page for a bit more information about this application of
   netCDF and email addresses of others who have used it ...
