Recovery realization

Crop Recoveries. Post-Column Derivatization (OPA-MERC). The good to excellent recoveries realized for all crops studied resulted from the efficiencies of both the cation exchange cleanup and anion exchange analytical columns, the care taken in the rotary evaporation of the samples ( 5°C condenser temp., maximum aspiration and 40°C water bath), and the selectivity of the OPA-MERC reagent. As seen in Table I, recoveries at 0.1 ppm for AMPA ranged from 61 to 82% and for GLYPH from 70 to 96%. [Pg.96]

Microwave extraction realized at 120 °C for 30 min with Hexane -Acetone (3 2 V/V) as the extraction solvent was identified as the most effective extraction procedure for isolation of TPH from biotic matrices. The aim of this research is to develop a silica gel and alumina fractionation procedure for plant sample extraction. Column chromatography with two solvents (chloroform and hexane dichloromethane) as a mobile phase were used for clean-up of extract. In this research the efficiency of recovery received from chloroform as a mobile phase. [Pg.270]

Finally, let s consider cash flow. Although cash flow does not have a direct effect on a company s revenues or expenses, the concept must be considered. If the project involves procurement costs, they often must be paid upon delivery of the equipment - yet cash recovery could take many months or even years. Three things about any project can affect a firm s available cash. First, cash is used at the time of purchase. Second, it takes time to realize financial returns from the project, through either enhanced revenues or decreased expenses. Depreciation expense is calculated at a much slower rate than the cash was spent. As a result of the investment, a company could find itself cash-poor. Even though cash flow does not directly affect revenues and expenses, it may be necessary to consider. [Pg.511]

The [nimary objective of the VOC-condensation system is to meet mass-recovery objectives. However, heat is a key element in realizing the mass objectives. Hence, the mass and heat interactions of the problem have to be identified and reconciled. This can be achieved by converting the VOC-recovery task from a mass-transfer problem to a heat-transfer duty. This can be accomplished by relating the... [Pg.250]

There may be some additional recovery from an LTX unit than would be realized from a straight two-stage flash sep" " — r"— increment is normally small and may not justify the increased equipment cost and operating complexity associated with an LTX unit. [Pg.150]

The total annual realizable heat recovery is 28,662 + 16,762 therms. This equals 45,424 therms (4542.4 MBtu, 4,792 GJ). This can be further equated to a savings in primary fuel input requirements. [Pg.97]

Sporicidal activity can be determined against spores in liquid suspension or against spores dried on carriers. In principle, techniques are similar to those described for bactericidal tests. However, it should be realized that spores must germinate and outgrow before colony formation is observed. For this reason, incubation of recovery media should be continued for several days. [Pg.241]

Sadvilkar et al. (1995) have studied condensation of benzaldehydes with acetophenones (Claisen-Schmidt reaction) in an aqueous medium, containing sodium butylmonoglycol sulphate and sodium salts of aromaticsulphonic acids as hydrotropes. A substantial improvement in the rate of reaction was realized, while product recovery was facilitated. [Pg.152]

The above-mentioned results demonstrate that the voltammetric maximum due to the adsorption of the transferring ion at one of two LM/W interfaces is requisite for the oscillation of AFwi-w2 or /wi-w2- However, the oscillation was not always realized with systems which gave maximum currents. The recovery of the concentration of the objective ion in the interfacial region of one phase from which the objective ion transfers to another is necessary in order to get the oscillation. If the ion pair which has been accumulated at the interface is desorbed to the phase to which the ion transfers, the oscillation cannot be realized. Taking into account this circumstance, the fact that the oscillation was not observed when in Eq. (11) was replaced by Br can be explained as follows. [Pg.624]

Chromatographic methods (essentially using ion-exchange resins) are especially useful for separating heparin from other glycosaminoglycans, for further analytical and structural characterization. However, it should be realized that recovery of heparin from resins is seldom quantitative,42 probably because of irreversible absorption of heparin fractions in the... [Pg.63]

Even though Jen was angry with me for a long time, she finally realized that she was slowly killing herself, and eventually she thanked me. She still sees a psychiatrist for her eating disorder, and may have to do so for a long time. She is safe and healthy again, but the road to recovery for this disorder is a rocky one. [Pg.84]

The tissue surrogates described here clearly represent a simplification of real FFPE tissues. However, they represent a useful and efficient construct for the evaluation and optimization of tissue extraction conditions for proteomic studies. More informative studies will likely be realized by using more complex tissue surrogates, which can be created by incorporating additional proteins into lysozyme solutions. Tissue surrogates comprised of up to five proteins have been successfully analyzed by MS (Fowler, unpublished data). Additionally, RNA, DNA, lipids, or carbohydrates can be added at nanomolar to millimolar concentrations to increase the complexity of the model system to better mimic whole tissue. The use of these more complex tissue surrogates should facilitate the development of protein recovery protocols optimal for proteomic investigation. [Pg.247]
