Issue Log:
Error: The value, "20-30g", 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: The value, "Male and female", for the subsection, "GENDER", in the "SUBJECT" section should be one of "Male", "Female", "Male, Female", "Hermaphrodite", or "N/A". Ignore this when more complicated descriptions are required.
Error: The value, "350ul/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, "25C", 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, "4ul for negative ion, 2ul for positive ion", 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 required property, "FLOW_GRADIENT", in the "CHROMATOGRAPHY" section  is missing.
