PC3 Peltier Cooler for Cyclonic Spray ChambersThe PC3 is a small, simple, and robust cooler for ICP-MS and ICP-0ES cyclonic spray chambers. The PC3 coolsthe outer walls of the cyclonic spray chamber to a constant temperature enhancing long-term signal stability,reducing polyatomic ion interferences such as oxides and reducing solvent loading especially when volatile organicsolvents are analyzed. The cyclonic spray chamber offers the advantages of low memory effects, fast rinse-outand, in many cases, higher sample transport efficiency.Create a part number by selecting the instrument model (zz), electrical outlet configuration (a), injector type (i),torch type (t), choose the mounting bracket (g), spray chamber material (d), auxiliary gas port (e), baffle (b), choosethe outlet for the ICP injector (u), and choose the nebulizer configuration (xx).Standard temperature settings are +2C/-5C. Any temperature settings can be accommodated. For custom settings,indicate the upper and lower settings after the part number using the following notation: [@T1@T2]Unless otherwise specified, PC3 Inlet System Kits will include one PFA-100 nebulizer and one PFA-ST nebulizer(xx = 21).PC3 Inlet System Kit ES-41zz-debu-aitg-xxPC3 Peltier Cooler (only) ES-4100Spray Chamber Options (debu)d = chamber material (normally 1 or 3)d = 1 quartz (High Purity)d = 2 polypropylened = 3 PFA (HF resistant)d = 4 glasse = auxilary port (mixed gas & organic solvents)e = 0 no aux. port (standard)e = 1 threaded aux. port, 1/4-28 (oxygen or make up gas)e = 2 aux. port, 2mm x 4 mmb = baffle typeb = 0 non-baffled (ICP-OES)b = 1 baffled (ICP-MS)u = outlet connector typeu = 1 ESI injector connection (straight connection)u = 7 TJA base torch connector (3/8" straight-tube outlet)u = 8 12/5 socket connectionu = 9 Perkin Elmer injector connection(e.g., connector for Ryton Spray Chamber)PC3 Kit Options (aitg)a = electrical outlet configurationa = 1 North America and Japana = 2 Europea = 3 UKa = 4 Chinaa = 5 Indiaa = 6 Australiai = injector typei = 0 No injectori = 1 ESI 1.5mm Quartzi = 3 ESI 1mm Quartzi = 2 ESI 2mm Quartzi = 4 ESI 1.8mm Sapphirei = 7 ESI 2mm Platinumi = 9 OEM Injectort = torch typet = 0 no torcht = 1 OEM Torcht = 2 ESI o-ring-free specifiedt = 3 ESI (o-ring specified)t = 4 One-piece quartzg = mounting bracket/ temperature settingsg = 0 standard without bracketg = 1 standard with bracketO-ring-free Teflon® PFA Cyclonic Spray ChamberMeinhard Glass Products700 Corporate Circle, Suite A Golden, Colorado 80401 USA1.800.MEINHARD 303.277.9776 Sales@meinhard.com www.meinhard.com
Apex High-Sensitivity SystemElemental Scientific has designed the new Apex family of high sensitivity and low backgroundsample introduction systems to increase signal intensity while often reducing relativebackground contamination for ICPMS and ICPAES analyses. The Apex improves sensitivityprimarily by increasing both sample transport efficiency and the quality of aerosol introduced tothe ICP instrument. The Apex controls background contamination by employing high-purity,inert, and o-ring-free wetted surfaces. When combined with a self-aspirating MicroFlow PFAnebulizer even aggressive and concentrated chemicals may be analyzed at very high sensitivityand very low contamination.Apex Q High-Sensitivity SystemThe Apex may be used with nebulizers operating over a wide range of sample flow rates from 20µL/min to over 1 mL/min. The nebulizers may be either self-aspirated or pumped.OperationLiquid samples are nebulized into a patent-pending spray chamber and desolvation system wherethe sample aerosol is efficiently conditioned to produce an intense and uniform aerosol that istransported to the ICP.When compared to conventional ICPMS sample introduction systems the Apex will typicallyincrease ICPMS sensitivity by approximately 10x when using a 300 µL/min nebulizer and byapproximately 3x when using a 100 µL/min nebulizer. These improvement factors are in spite ofthe lower Apex sample consumption rate. ICP-MS detection limits are in the sub-ppt to sub-ppqrange for most elements.ICPAES detection limits can be improved by up to a factor of 6-10 when operating at 1 ml/minusing a MicroFlow PFA or PolyPro ST nebulizer together with the Apex. Alternatively, thecombination of a low flow nebulizer with the Apex maintains ICP-AES sensitivity while reducingsample consumption by a factor of 5 to 10, improving ICP-AES determinations when the volumeof sample is limited.
