The Systematic Error in Photometric Set-point Titrations of Submicromolar Amounts of Calcium and Zinc
Although reproducible results can be obtained in photometric set-point titrations of submicromolar amounts (5 -lo+ M and higher) of calcium(I1) and zinc(I1) by using an ? automatic titrator, the systematic error can be considerable. This error is partly intrinsic ; in nature, but there is an additional error caused by dilution in successive titrations_ Accurate values can be obtained only when ...
متن کاملNote on Set Cover
Greedy: Θ(min(logd,q)): Θ(H(d)) (this also implies O(logn), n is number of elements). (Note: Feige [3] prove that there is no substantially improvement (for greedy algo).) Also O(q) and exists tight example (section 2.5); so, Θ(q) in general. Note that this bound is asymptotically tight (see Vazirani’s book [10] section 29.9) Slav́ık [9] also gives exact analysis lnn− lnlnn+Θ(1). LP Rounding: O(...
متن کاملA note on maximally repeated sub-patterns of a point set
We answer a question raised by P. Brass on the number of maximally repeated subpatterns in a set of n points in Rd. We show that this number, which was conjectured to be polynomial, is in fact Θ(2n/2) in the worst case, regardless of the dimension d.

متن کاملAutomated spectrophotometric analyzer for rapid single-point titration of seawater total alkalinity.
An automated analyzer was developed to achieve fast, precise, and accurate measurements of seawater total alkalinity (AT) based on single-point titration and spectrophotometric pH detection. The single-point titration was carried out in a circulating loop, which allowed the titrant (hydrochloric acid and bromocresol green solution) and a seawater sample to mix at a constant volume ratio. The di...
