Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: The value, "320 deg. Cel.", for the subsection, "CAPILLARY_TEMPERATURE", in the "MS" section 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, "-3.0 kv", for the subsection, "CAPILLARY_VOLTAGE", in the "MS" section 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, "250 deg. Cel.", for the subsection, "ION_SOURCE_TEMPERATURE", in the "MS" section should be a number 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, "Negative", for the subsection, "IONIZATION", in the "MS" section should not be "positive" or "negative". "ION_MODE" is where that should be indicated. Error: An empty value or a null value was detected for the subsection, "MS_COMMENTS", in the "MS" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether. Error: An empty value or a null value was detected for the subsection, "MS_RESULTS_FILE", in the "MS" section, for the "UNITS" attribute. A legitimate value should be provided for this required subsection. Error: The value, "200 µl/min", for the subsection, "FLOW_RATE", in the "CHROMATOGRAPHY" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['mL/min', 'uL/min', 'μL/min']. Ignore this when more complicated descriptions are required. Error: The value, "22 deg. Cel.", for the subsection, "COLUMN_TEMPERATURE", in the "CHROMATOGRAPHY" section 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, "10 µl", for the subsection, "SAMPLE_INJECTION", in the "CHROMATOGRAPHY" section 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. Error: The value, "22 deg. Cel.", for the subsection, "INJECTION_TEMPERATURE", in the "CHROMATOGRAPHY" section 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'] or "room temperature". Ignore this when more complicated descriptions are required. Error: The value, "20 minutes", for the subsection, "ANALYTICAL_TIME", in the "CHROMATOGRAPHY" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['min']. Ignore this when more complicated descriptions are required. Error: The value, "22 deg. Cel.", for the subsection, "TRANSFERLINE_TEMPERATURE", in the "CHROMATOGRAPHY" section should be a number 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, "10 µl", for the subsection, "SAMPLE_LOOP_SIZE", in the "CHROMATOGRAPHY" section 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. Error: The value, "100 µl", for the subsection, "SAMPLE_SYRINGE_SIZE", in the "CHROMATOGRAPHY" section 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.
