Match, matching

If two or more different cuvettes are used in an analysis, one should be sure that they are matched. Matched cuvettes are identical with respect to pathlength and reflective and refractive properties in the... 

Chemical interferences are the result of problems with the sample matrix. For example, viscosity and surface tension affect the aspiration rate and the nebulized droplet size, which, in turn, affect the measured absorbance. The most useful solution to the problem is matrix matching, matching the matrix... 

Several things can go wrong in this matching. Matches of calculated and experimental Z-(0 plots are seldom exact. Personal judgment becomes involved. One researcher may consider Z-(0 plots using a certain circuit satisfactory, but a more critical researcher may not accept that there is a fit and point to the use of parameters (perhaps values of the surface state C s and A s) that are too far away from those known by independent methods to be likely for the system concerned. 

Newer technology allows for opaque, translucent, transparent samples as well as multiple film thicknesses for both reflectance and transmittance measurements. The newer technology provides a spectral match (matches spectral curve of the sample at each wavelength across the visible spectrum 360-740 nm). The advantage of spectral matching is its ability to match both color and opacity from a single database. 

Hydrophobic matching Match between the length of the hydrophobic region of a transmembrane protein and the thickness of the bilayer.

Safety Match Match specially designed to light only when struck against a specially prepared surface. 

Wender et al. reported an interesting example that appears to exhibit a cooperative or matched-matched case for the chiral Lewis acid-catalyzed HDA of an aldehyde bearing a chiral auxiliary and Danishefsky s diene (Scheme 65) [119]. Subjecting chiral aldehyde 245 and siloxydiene 231 to Jacobsen s catalyst resulted in the formation of 2,3-DHP 246 in 88 % yield with excellent diastereoselectivity (dr = 33 1).
