Issue Log:
Error: The value, "230°C", in ["MS"]["ION_SOURCE_TEMPERATURE"] 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, "70eV", in ["MS"]["IONIZATION_ENERGY"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['eV']. Ignore this when more complicated descriptions are required.
Error: An empty value or a null value was detected in ["MS"]["MS_COMMENTS"]. Either a legitimate value should be provided for this key, or it should be removed altogether.
Error: The value, "1mL/min", in ["CHROMATOGRAPHY"]["FLOW_RATE"] 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, "250°C", 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, "0.2µl", 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.
Error: The value, "230°C", in ["CHROMATOGRAPHY"]["TRANSFERLINE_TEMPERATURE"] 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 required property, "FLOW_GRADIENT", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_A", in ["CHROMATOGRAPHY"] is missing.
Error: The required property, "SOLVENT_B", in ["CHROMATOGRAPHY"] is missing.
Error: The ["MS_METABOLITE_DATA"]["Metabolites"] table does not have a column for "Metabolite". It is likely misspelled or using a common incorrect substitute.
