For example, if the sample contains approximately 300 mg/L BOD and the laboratory altitude is 305 m (1000 ft), the maximum sample volume is 8 mL. If the sample contains approximately 40 mg/L BOD and the laboratory altitude is 305 m (1000 ft), Webspectrophotometer is slightly inaccurate or set slightly inaccurately. Absorbance and Transmittance Transmittance is simply the percentage of light impinging on a solution that passes through the solution and emerges to be detected by the instrument.
