Chemistry and Biology

Example script showing how to use the ChemistryBiology class to extract information from the KCDB.

Script

"""Search the "Chemistry and Biology" metrology domain of the KCDB."""

from msl.kcdb import ChemistryBiology

chem_bio = ChemistryBiology()

#
# Get all reference data for the "Chemistry and Biology" metrology domain
#
print(f"Getting all reference data for {chem_bio.DOMAIN.name}...")
countries = chem_bio.countries()
print(f"  There are {len(countries)} countries")
analytes = chem_bio.analytes()
print(f"  There are {len(analytes)} analytes")
categories = chem_bio.categories()
print(f"  There are {len(categories)} categories")

#
# Find all analytes that are related to "boron"
#
print("All analytes related to 'boron'...")
boron_analytes = chem_bio.filter(analytes, "boron")
for analyte in boron_analytes:
    print(f"  {analyte}")

#
# Search the "Chemistry and Biology" database for NMIs that are capable of
# performing measurements with "boron" analytes and print some information
# about each NMI
#
print("All NMIs that have capabilities with 'boron' analytes...")
for analyte in boron_analytes:
    result = chem_bio.search(analyte=analyte)
    for data in result.data:
        print(f"  {data.nmi_code} ({data.category_value}): {data.nmi_service_code}")

Output

Running this script outputs the following, although, some values may change from what you observe when you run this script since information in the KCDB is continually changing.
