A toluene solution (1.50 mg / L) shows an absorbance of 0.30 in a cuvette with a 0.025 mm optical path. Calculate the limit of detection (in ppb) for toluene if the noise with the solvent spectrum is 0.002 absorbance units in a 0.050 mm cuvette.
You have a concentrated sample solution of a new wine from a winery to analyze for malic acid content. once you have worked up the sample and done one 5x dilution you record an absorbance of .395 at the analytical wavelength of the malic acid. the molar absorptivity coefficient E of the malic acid for this method of measurement is 15.84 mM-1cm-1. What was the molarity of malic acid in original wine sample mM?
Maria was tasked to determine the concentration of a Fe2(SO4)3 solution. She prepared 5 different standards of Fe2(SO4)3 using the table below as her guide. She ran the standards and the unknown solution through UV-VIS spectroscopy and recorded the absorbances of each solution. HINT: use the dilution equation to determine the concentration of Fe2(SO4)3 in each test tube before preparing the standard curve. NOTE: No need to force the line to pass through zero. Just graph the data as is. What is the slope of the line of the standard curve from the given data? What is the concentration of the unknown solution?
A green solution containing Ni+2 ions absorbs 580 nm light. Undiluted, a sample of this solution sampled in a 1.00 cm diameter cuvette has an absorbance of 0.9765 a.u.. If the molar absorptivity coefficient for Ni+2 is 6.3 x 104 M -1 cm -1 at 580 nm, how much of the original stock Ni+2 solution (in mL) needs to be added to water to create a total dilute solution volume of 10.00 mL that measures an absorbance of 0.146 a.u. at 580 nm? Report your answer to 3 significant figures. Do not include the "mL' unit label in your response
In the analysis conducted with flame AAS, standard solutions of the X-type are analyzed individually and the absorbance values obtained are plotted against concentration (ppm). It was seen that the slope of the calibration line obtained was 0.0925. The standard deviation of the absorbance values obtained by reading the blank 10 times under the same conditions was calculated as 0.00183 ppm. According to this; For the X-type calculate the following: a) LOD b) LOQ c) Sensitivity
