Refimprove date February 2007 Expert subject Pharmacology date February 2009 Image Luerlock syringefilter.jpg thumb 250px A 0.2 micrometre luer lock syringe filter that is not a wheel filter type shape. A syringe filter sometimes called a wheel filter if it has a wheel like shape is a single use filter cartridge. It is attached to the end of a syringe for use. Syringe filters may have Luer lock fittings, though not universally so. The use of a needle is optional where desired it may be fitted to the end of the syringe filter. A syringe filter generally consists of a plastic housing with a membrane which serves as a filter. The fluid to be purified may be cleaned by drawing it up the syringe through the filter, or by forcing the unfiltered fluid out, through the filter. Forms In scientific applications, the most common sizes available are 0.2 or 0.22 micrometre µ m and 0.45 m pores. These sizes are sufficient for HPLC use. The smallest known sterile syringe microfilter is Anotop 10 Syringe Filters Plus with pore size 0.02 m. Membrane diameters of 10 mm, 13 mm, 25 mm are common as well. Some syringe filters for small volumes may be not resemble a wheel at all. The syringe filter body may be made of such materials as polypropylene and nylon . The filter membrane may be of PTFE , nylon , or other treated products for specific purposes. Most manufacturers publish compatibility wallcharts advising users of compatibility between their products and organic solvents or corrosive liquids e.g. trifluoroacetic acid . Application Syringe filters may be used to remove particles from a sample, prior to analysis by High performance liquid chromatography HPLC . Particles easily damage an HPLC due to the narrow bore and high pressures within. Syringe filters are quite suitable for Schlenk line work, which makes extensive use of needles and syringes.

The Calder Center is a protected forest preserve located convert 30 mi km north of New York City in Armonk, New York , and is the only full time ecological research field station in the New York metropolitan area . History The Louis Calder Center was founded in 1967 when Louis Calder donated his convert 113 acre km2 sing on estate to Fordham University. Buildings have since been constructed, renovated, and modernised. Buildings The Louis Calder Center consists of 19 buildings including Calder Hall A 27 room stone mansion which houses seminar rooms, a library, herbarium, insect collection, guest rooms, kitchen, and dining room. McCarthy Laboratories a building where a great amount of the analysis of samples is carried out. The lab includes growth chambers, a nutrient autoanalyzer , gas chromatograph , High performance liquid chromatography HPLC , carbon nitrogen analyzer , fluorescence and phase microscope s, spectrophotometre s, autoclave s, electronic balances, refrigerator s, centrifuge s, and other scientific equipment. Greenhouses Lakeside Lodge Routh House Calder Lake Calder Lake is a 4 hectacre mesoeutrophic lake located within the Louis Calder Center. The lake bottom is more than half covered by a submeresed macrophyte community, including Vallisneria americana , Elodea canadensis , Potamogeton amplifolius , and Najas flexilis . Since Calder Lake is relatively small, the surrounding flora including Quercus rubra , Quercus prinus , Acer rubrum , Fagus grandifolia , and Cornus florida plays a significant role in its ecology, as falling leaves add nutrients to the water. The production rates of bacteria and larger phytoplankton in the lake are limited by the supply of inorganic phosphorus . Dissolved organic carbon exists between 4 6 mg C L in the lake.

context date September 2008 Unreferenced date March 2008 The most common chemical equilibrium systems involve reactants and products in the same phase either all gases or all solutions. However, it is also possible to get equilibria between substances in different phases, such as two liquids that do not mix are immiscible . Partition equilibria are described by Nernst law. Example For example, ammonia NH sub 3 sub is soluble in both water aq and the organic solvent trichloromethane CHCl sub 3 sub two immiscible solvents. If ammonia is first dissolved in water, and then an equal volume of trichloromethane is added, and the two liquids shaken together, the following equilibrium is established K sub c sub NH sub 3 sub sub CHCl3 sub NH sub 3 aq sub where K sub c sub is the equilibrium constant The equilibrium concentrations of ammonia in each layer can be established by titration with standard acid solution. It can thus be determined that K sub c sub remains constant, with a value of 0.4 in this case. Partition coefficient main Partition coefficient This particular kind of equilibrium constant measures how a substance distributes or partitions itself between two immiscible solvents. It is called the partition coefficient or distribution coefficient. Polar and non polar substances Substances that are Ionic compound ionic or Chemical polarity polar are more soluble in water than in non polar organic solvents and vice versa. Partition equilibrium chromatography Partition equilibrium chromatography is a type of chromatography that is typically used in gas chromatography GC and high performance liquid chromatography HPLC . The Stationary phase chemistry stationary phase in GC is a high boiling liquid bonded to solid surface and the mobile phase is a gas.

Taxonomic name not approved yet. Growth characteristics, acid fastness and 16S rRNA gene sequencing results were consistent with those of the genus Mycobacterium . Biochemical reactions, growth characteristics and mycolic acid profiles HPLC resembled those of Mycobacterium shottsii , a non pigmented mycobacterium also isolated during the same epizootic. Sequencing of the 16S rRNA genes, the gene encoding the exported repeated protein erp and the gene encoding the 65 kDa heat shock protein hsp 65 and restriction enzyme analysis of the hsp 65 gene demonstrated that this group of isolates is unique. Insertion sequences associated with Mycobacterium ulcerans , IS2404 and IS2606, were detected by PCR. These isolates could be differentiated from other slowly growing pigmented mycobacteria by their inability to grow at 37 C, production of niacin and urease, absence of nitrate reductase, negative Tween 80 hydrolysis and resistance to isoniazid 1 g ml 1 , p nitrobenzoic acid, thiacetazone and thiophene 2 carboxylic hydrazide. On the basis of this polyphasic study, it is proposed that these isolates represent a novel species, Mycobacterium pseudoshottsii sp. nov.

Orphan date October 2008 File LogP200.jpg right 200px thumb Flow reaction system for automated forced degradation testing Forced degradation or accelerated degradation is a process whereby the natural degradation rate of a product or material is increased by the application of an additional stress. Introduction Forced degradation studies are used to identify reactions which may occur to degrade a processed product. Usually conducted before final formulation, forced degradation uses external stresses to rapidly screen material stabilities. Longer term storage tests are usually used to measure similar properties when final formulations are involved because of the stringent FDA regulations. These tests are generally more expensive because of the time involved than forced degradation which is therefore used for rapid selection and elimination tests. Common stresses There are a number of common stresses which are used to pH acid base Chemical processes are often catalysed by the presence of acids and bases. The exposure of materials to these can therefore accelerate degradation reactions. Temperature In accordance to Arrhenius equation arrhenius kinetics , increasing temperature increases the rate of any degradation process. Temperature is often used in conjunction with other stresses to increase reaction rates.

High performance thin layer chromatography HPTLC is an enhanced form of thin layer chromatography TLC . A number of enhancements can be made to the basic method of thin layer chromatography to automate the different steps, to increase the resolution achieved and to allow more accurate quantitative measurements. Automation is useful to overcome the uncertainty in droplet size and position when the sample is applied to the TLC plate by hand. One recent approach to automation has been the use of piezoelectric devices and inkjet printers for applying the sample. ref cite journal title Miniaturized planar chromatography using office peripherals journal Analytical Chemistry journal Analytical Chemistry year 2010 first Gertrud E. last Morlock coauthors Claudia Oellig, Louis W.
