These specialized devices - which reduce total solvent transport to an RF plasma,
and which can be operated at a considerable distance from a plasma torch,
are available from EPOND :

the  APEX-Q -   increases the power of ICP-MS analysis by an order of magnitude     -   stable sensitivity increase of 10x or more   -   oxides reduced by > 5x by APEX alone   -   sample consumption reduced   -   available with quartz or PFA sample passages   -   compact, O-ring free   -   see publication by  Fragniere et al. :      J. Anal. At. Spectrom.,  (2005),  Vol.20,  pp. 626-630   -   APEX-IR model available for Isotope Ratio measurements   -   APEX-E model available for ICP-OES

the  Spiro-TMD,  ACM  and  AREO membrane modules  -   decrease CeO/Ce ratios to as low as 0,03%     -   all 3 modules are designed to enhance the APEX   -   oxides reduced by > 50x   -   Spiro-TMD  can operate stand-alone   -   ACM Module uses either Ar or N2 sweep gas   -   Spiro-TMD and ACM are electrically regulated   -   compact, O-ring free and HF-resistant   -   internal membranes easily changed   -   modules can be flush-cleaned with acid

the  PC3 -   electrically thermostatted spray chamber     -   stable, compact and cost-effective   -   no external cooler required   -   reduces oxide interferences for ICP-MS analyses   -   user-settable to +2C/-5C for aqueous or organic samples   -   other temperatures are programmable   -   better sensitivity than some 'Scott-type' spray chambers   -   quartz and HF-resistant chambers available   -   Reaches -20 deg. C. with PC3-LT option   -   O-ring free connections   -   available for  all  ICP types   -   priced from $2190,-

the  QuDIN -   Quasi-Direct Injection system for very low uptakes     -   supplied with low-uptake concentric nebulizer   -   Connects directly to base of ICP torch   -   minimizes sample-passage 'dead-space'   -   benefits of DIN, without the downside   -   'SEDNA' on-line sample uptake monitor available   -   derived from the  'TISIS',  by  Todoli and Mermet :      J. Anal. At. Spectrom.,  (2002),  Vol.17,  p.345
