Either a legitimate value should be provided for this key, or it should be removed altogether. Error: An empty value or a null value was detected in ["STUDY"]["NUM_FEMALES"]. Either a legitimate value should be provided for this key, or it should be removed altogether. Error: An empty value or a null value was detected in ["SAMPLEPREP"]["SAMPLE_DERIVATIZATION"]. Either a legitimate value should be provided for this key, or it should be removed altogether. Error: The value, "300", in ["MS"]["CAPILLARY_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, "3.5 KV", in ["MS"]["SPRAY_VOLTAGE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['kV']. Ignore this when more complicated descriptions are required. Error: The value, "45", 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. Error: The value, "10", in ["CHROMATOGRAPHY"]["INJECTION_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'] or "room temperature". Ignore this when more complicated descriptions are required. Error: The value, "3.50 KV", in ["CHROMATOGRAPHY"]["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, "3.50 KV", in ["CHROMATOGRAPHY"]["RUNNING_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, "300 µL", in ["CHROMATOGRAPHY"]["WEAK_WASH_VOLUME"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['μL', 'uL'].
