POSITIVE_CONTROL	MSIO:0000008	Control providing known positive signal
NEGATIVE_CONTROL	MSIO:0000007	Control providing baseline/no signal reference
LONG_TERM_REFERENCE	MSIO:0000006	Stable reference for cross-batch comparisons
BLANK	None	Sample containing only solvent/matrix without analyte
QUALITY_CONTROL	None	Sample with known composition for system performance monitoring
