HPLC Valves

A single modular, versatile, effortless and sensitive IonQuest ion chromatography system

Neutral alumina columns are useful when samples are acid sensitive and prone to degradation on normal phase silica gel. Acid and basic alumina columns are useful when purification of a compound with those properties is considered. This avoids the solvent swapping and additional extraction, washing, and concentration involved in recovering target compounds from collected fractions containing a mobile phase modifier such as tri…

The TharSFC Mass Directed SFC–MS Prep 100 System is the automated way to improve a laboratory's efficiency and turn–around times.

Thar designs and manufactures high pressure pumps ideally for high pressure and high temperature applications, such as supercritical fluid chromatography (SFC), HPLC, supercritical fluid extraction (SFE), particle formation, reactions, solvent extractions. The pumps can be controlled using a hand-held display (included) or PC via the built-in RS232C interface. The high pressure pump can be used in conjunction with additional…

WTW offers a wide range of Ion-Selective Electrodes and instruments. Series 500 electrodes are used in combination with a separate reference electrode. And now WTW introduces our Series 800 quality combination ISE’s! These precise electrodes combine a reference and ion selective electrode in one unit. The convenience of this design allows for ease of use even in small sample volumes.

The pH/mV and ionmeter pH/ION 340i offers the highest degree of flexibility possible. For pH measurements the instrument can be calibrated manually or automatically and offers simultaneous display of pH and temperature. For measurements with ion-selective electrodes the pH/lON 340i offers concentration display in mg/l. Direct display in mV to ±999.9 mV in 0.1 mV steps; and to ±1999 mV in 1 mV steps. Of course, even in these…
