The precision of eight individual syringes using hydrocarbon analysis. A methane gas standard was diluted by the eight Borgwaldt RM20S syringes and precision was calculated as a function of accuracy of dilution delivery. A - syringe precision at a dilution of 1:193 (smoke:air, v/v) against a target value of 520 ppm methane gas standard, n = 15. B - syringe precision at a dilution of 1:500 (smoke:air, v/v) against a target value of 200 ppm methane gas standard, n = 15, * = outliers.
