| 20090302230 | Use of a Broad Band UV Light Source for Reducing The Mercury Interference in Ozone Measurements - The present disclosure provides a means of greatly reducing the interference of mercury vapor in the UV absorbance measurement of ozone. Currently, commercial ozone monitors make use of a low pressure Hg lamp as the radiation source. Because the lamp spectral lines are extremely narrow and resonant with the Hg vapor absorption spectrum, ozone monitors typically detect Hg with approximately three orders of magnitude greater sensitivity than ozone itself. The replacement of the low pressure mercury lamp with a broad band UV source centered near 254 nm greatly reduces the Hg interference. The optimal band width (FWHM) for the radiation source is approximately 1-10 nm. For band widths in this range, the Hg interference is reduced by a factor of 140 (for 1 nm) to 1,400 (for 10 nm) with minimal effect on the sensitivity toward ozone and linear dynamic range. Although conventional broad band sources such as medium and high pressure Hg lamps, hydrogen lamps, deuterium lamps and xenon arc lamps could be used in conjunction with a monochromator and/or band pass filter to produce radiation of the desirable band width, recently developed UV LEDs are used in the disclosed embodiments because of their small size and low power consumption. | 12-10-2009 |
