The present application is a continuation of and claims priority under 35 U.S.C. § 120 to U.S. patent application Ser. No. 10/366,540, filed Feb. 12, 2003. U.S. patent application Ser. No. 10/366,540 is based upon and claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 60/357,264, filed Feb. 12, 2002, which is incorporated in its entirety by reference herein. U.S. patent application Ser. No. 10/366,540 is also a continuation-in-part from and claims priority under 35 U.S.C. § 120 to U.S. patent application Ser. No. 10/319,409, filed Dec. 12, 2002, incorporated in its entirety by reference herein, which was based on and claimed priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application No. 60/341,435 filed Dec. 14, 2001 and U.S. Provisional Patent Application No. 60/357,264 filed Feb. 12, 2002.
As illustrated by FIG. 6, providing the absorption spectrum further comprises determining the absorption spectrum from the transmittance spectrum in an operational block 230. In certain embodiments, the relation between the transmittance spectrum and the absorption spectrum is expressed as: A ⁡ ( λ ) = ln ⁡ ( 1 T ⁡ ( λ ) )
13. The method of claim 1, wherein the protein comprises a material from the group consisting of: hemoglobin, albumin, globulin, and ferritin.
19. The method of claim 1, further comprising subtracting a protein contribution corresponding to the protein from the corrected absorption spectrum, thereby providing a twice-corrected absorption spectrum substantially free of contributions from water and from the protein.
20. The method of claim 19, wherein subtracting the protein contribution comprises:
32. A method of determining an analyte concentration in a biological sample, the method comprising:
filling the cuvette with the biological sample and measuring a sample absorbance spectrum of the cuvette containing the biological sample; and
calculating the analyte concentration in the biological sample using the reference absorbance spectrum and the sample absorbance spectrum.
33. The method of claim 32, wherein filling the cuvette with saline and measuring the reference absorbance spectrum is performed prior to filling the cuvette with the biological sample and measuring the sample absorbance spectrum.
34. The method of claim 33, further comprising filling the cuvette with saline and measuring the reference absorbance spectrum after filling the cuvette with the biological sample and measuring the sample absorbance spectrum.
35. The method of claim 32, wherein filling the cuvette with saline and measuring the reference absorbance spectrum is performed after filling the cuvette with the biological sample and measuring the sample absorbance spectrum.
36. The method of claim 32, wherein calculating the analyte concentration comprises calculating an optical pathlength of the cuvette.
37. The method of claim 32, wherein calculating the analyte concentration comprises calculating instrument drift and baseline deviations using the reference absorbance spectrum.
