Issue Log:
Error: The value, "20-26g", for the subsection, "WEIGHT_OR_WEIGHT_RANGE", in the "SUBJECT" section should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['g', 'mg', 'kg', 'lbs']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected for the subsection, "ADDITIVES", in the "COLLECTION" section. Either a legitimate value should be provided for this subsection, or it should be removed altogether.
Error: The value, "Medium", for the subsection, "COLLISION_GAS", in the "MS" section should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required.
Error: The value, "500°C", for the subsection, "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 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, "50°C", 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: Unknown or invalid subsection, "SOLVENT_C", in the "CHROMATOGRAPHY" section .
