Recent advances in room-tempemtun:, visible and near-IR diode laser sources for tclecomnlllnication, optical data storage applications are enabling combustion diagnostics systcm based on diode laser absorption spectroscopy. In contrast to some tradilional sampling-based gas-sensing instmments, tunable diode laser absorption spectroscopy syslem is ad,'antageous because of their non-invash'e nature. high sensitivity, fast response time and real-time measurement capability. So. combined with fiber-optics and high scnsitive dctcction strategies. compact and ponablc sensor system are now appearing for a ,'aricly of applications. The objective of Ihis research is 10 take advanlage of distribuled fccd-back diode lascr and mcasure the co, conccntration (by using dircct absorption and wa,'elcngth modulation spectroscopy methods). In addition to survey spectra of co, bands and spectroscopic parameters bctween 1565 and 1579 nm were computed at tcmperatures between 296 and 1200 K (by using HITRAN 2000 databasc), II expellmcntally fouud oul Ih.1t the fC:ltufes of direct absorplion and wavelength modulation spectroscopy methods.

The abnormal b-globin of propositus(Hwang, 18 years old, boy) was purified by urea CM cellulose column chromatography and then identified by urea-polyacetate membrane electrophoresis. The purified abnormal b-globin was analyzed by alpha plus amino acid analyzer and the following results were obtained : No of gly residues is 13, ala 15, val 18, leu 18, ser 5, thr 7, asp 18, glu 11, arg 4, lys 10, his 9, pro 7, phe 7, tyr 2 and met 1. On the bases of the above results it was assumed that the abnormal b-globin, propositus Hwang, was resulted in substitution of amino acid arg for lys.
