Issue Log:
Error: An empty value or a null value was detected in ["PROJECT"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["STUDY"]["PHONE"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["COLLECTION"]["COLLECTION_SUMMARY"]. A legitimate value should be provided for this required key.
Error: An empty value or a null value was detected in ["TREATMENT"]["TREATMENT_SUMMARY"]. A legitimate value should be provided for this required key.
Error: The value, "4.45", in ["MS"]["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, "N2", in ["MS"]["COLLISION_GAS"] should be one of "Nitrogen" or "Argon". Ignore this when more complicated descriptions are required.
Error: The value, "50", in ["MS"]["GAS_PRESSURE"] should be a number followed by a space with a unit (ex. "5 V") from the following list: ['psi', 'psig', 'bar', 'kPa']. Ignore this when more complicated descriptions are required.
Error: The value, "48", in ["MS"]["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, "3.5", 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 required property, "UNITS", in ["MS"]["MS_RESULTS_FILE"] is missing.
Error: The value, "350?L/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, "30", 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, "10?L", 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 minutes", in ["CHROMATOGRAPHY"]["ANALYTICAL_TIME"] 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, "45", 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, "20?L", in ["CHROMATOGRAPHY"]["SAMPLE_SYRINGE_SIZE"] 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.
