Rheodyne MRA100-100 HPLC Flow Splitter

Product Information

Rheydyne Custom MRA100-100 Flow splitter. HPLC flow splitters are often used to couple mass spectrometers to liquid chromatographs to reduce the amount and concentration of sample delivered to a mass spectrometer. This is especially useful in automated systems to avoid unwanted MS inlet overload. Splitting is also required for applications in which a second detector or a fraction collection device is used parallel to the MS. LC/MS flow splitting is typical, for example, in the automated analysis of combinatorial libraries, drug metabolites, and the characterization of impurities. The Rheodyne MRA100-100 boasts an extensive range of programmable split ratios, accurate and consistent split ratios independent of changes in temperature, and switching frequency range: 0.2 Hz to 2.0 Hz. It also provides nominal aliquot sizes of 22 nL, 100 nL, and 300 nL and a pressure rating of 6.9 MPa (69 bar, 1000 psi). The MRA100-100 is made of stainless steel and RPC-8*, and its communications are automated operation by Input Line Control or RS-232. An auxiliary LC pump is required to provide an independent flow source to the MS and the maximum benefits available from the MRA.
