Conditions:

Room Temp: 25 and 29 °C

Compiler:

A. Maczynski

Methodology:

The dynamic coupled column liquid chromatography (DCCLC) method was based on generating saturated solutions by pumping water through a column packed with glass beads that have been coated with the component [1] (generator column). The concentration of [1] in the effluent of the generator column was measured by a modification of the coupled column liquid chromatographic process that has been described in [1].

Sample Information:

1. Commercial product; less than 3% impurities.
2. Distilled over $\ce{KMnO4}$ and $\ce{NaOH}$ and passed through a column packed with XAD-2 (Rohm and Hass, Philadelphia, Pa.)

Measurement Errors:

Ambient temperature: ±0.05°C
Mass concentration (m/v) (1): ±0.002 mg(1)/kg(2) (standard deviation)
