Precision data for 1.79 g/mL PIR.

	Intraday			Interdays
	Day 1 ()	Day 2 ()	Day 3 ()	Whole days ()
Mean	0.284	0.286	0.286	0.285
SD	0.004	0.004	0.004	0.005
RSD%	1.581	1.494	1.476	1.827
CI ()	±0.004	±0.003	±0.003	±0.002

SD is standard deviation, RSD is relative standard deviation, CI is confidence interval, and is probability level of 95% for experiments (intraday) and for experiments (interdays).
