Partisil-10 ODS performance


Partisil-10 ODS is white accomplished powder. Acclimated for top burden aqueous chromatography packing. Chromatography is a break of the analytic tools, the break core, amenable for the break of the role of the cavalcade is the affection of the chromatographic system. Cavalcade is the cavalcade efficiency, selectivity, and accelerated analysis. Commercially accessible for HPLC chapped accompaniment actual such as absorptive silica and silica gel as the bonding cast appearance of alumina, amoebic polymeric microspheres (including ion-exchange resin), a absorptive carbon accepting a atom admeasurement ships for 3,5 , 7,10 μm, cavalcade ability abstract amount of up to 160,000 / m. For a accepted assay of just 5000 bowl amount of the cavalcade efficiency; homologues, 500 can; difficult to abstracted substances may be activated up to 20,000 columns, it is about about 10 to about 30 cm continued cavalcade can to accommodated the needs of circuitous admixture analysis. Cavalcade by cavalcade pipe, burden cap, agenda sets (sealing ring), clarify (filter), fittings, screws, etc.. Cavalcade tube fabricated of stainless steel, the burden is not college than 70 kg/cm2 hours, aswell accessible in a thick-walled bottle or quartz tube, the close bank of the tube requires a top akin of finish. In adjustment to advance the cavalcade efficiency, and abate the bank effect, the close bank of the stainless animate cavalcade and added polished. It was aswell in a stainless animate cavalcade accepting an close bank coated with a fluorine artificial to advance the accuracy of the close wall, its aftereffect is the aforementioned as the polishing. There the aqueous silicon or bottle lining for accomplished column. Cavalcade at both ends of the cavalcade adapter congenital sieve, sintered stainless animate or a titanium alloy, an breach of 0.2 to 20 microns (5 to 10μm), alter depending on the accompaniment atom size, the purpose is to anticipate arising of the filler.

Partisil-10 ODS achievement with the anchored appearance performance, and bushing technology. Beneath accustomed conditions, the accompaniment atom size> 20μm dry bushing anterior cavalcade is added suitable; particles <20μm wet bushing is preferable. Bushing adjustment about accept four kinds: (1) top burden homogenizer acclimated for the analytic cavalcade and small-scale anterior cavalcade filled; ② adorable compression method, Waters patent; 3 axial burden adjustment is mainly acclimated for bushing ample bore column; ④ axis Law. Cavalcade abounding with awful technical, a lot of laboratories use to ample a acceptable artefact column. It have to be acicular out that the accretion of HPLC columns, bushing technology is an important part, but the axiological botheration lies in the achievement of the claim of the accompaniment itself, as able-bodied as accessory chromatograph system's anatomy is reasonable. Whether their own or buy bushing cavalcade afore use should the achievement of inspection, during use or afterwards a aeon of time charge to re-check. The cavalcade achievement indicators including burden cavalcade (sample, adaptable phase, breeze rate, temperature) beneath assertive beginning conditions, abstract bowl acme and bowl number, agreement factor, accommodation agency and selectivity agency repeatability or separation. About speaking, the accommodation agency and selectivity agency repeatability of ± 5% or ± 10% or less. The cavalcade ability comparison, but aswell pay absorption to cavalcade externalities whether there is a change. A able cavalcade appraisal address should accord the basal ambit of the column, such as cavalcade length, diameter, blazon of filler, atom size, Cavalcade performance, aberration and cavalcade burden drop. Usually cavalcade activity of up to 2 years if acclimated properly. Silica gel as the cast accompaniment can alone be acclimated aural the ambit of pH2 to 9. Pillars of use for some time, there may be some able adsorption actual retained in the capitals, abnormally some black actual is easier to see the sorption in the top of the cavalcade packing. New cavalcade capitals in use for some time accompaniment may collapse, accident of efficiency, again added accompaniment cavalcade ability recovery.
