Issue Log:
Error: The required property, "SUBJECT_SPECIES", in ["SUBJECT"] is missing.
Error: An empty value or a null value was detected in ["COLLECTION"]["ADDITIVES"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "3500", in ["MS"]["CAPILLARY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V', 'kV']. Ignore this when more complicated descriptions are required.
Error: The value, "125", in ["MS"]["FRAGMENT_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "Negative", in ["MS"]["IONIZATION"] should not be "positive" or "negative". "ION_MODE" is where that should be indicated.
Error: The value, "750", in ["MS"]["OCTPOLE_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['V']. Ignore this when more complicated descriptions are required.
Error: The value, "40", in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: The value, "5 µL", in ["CHROMATOGRAPHY"]["SAMPLE_INJECTION"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL']. Ignore this when more complicated descriptions are required.
