- Description
- Liquid Chromatograph-Inductively Coupled Plasma/Mass Spectrometer (LC-ICP/MS) This notice replaces the initial notice posted in the morning of 07/05/2005. Please call 513 487-2049 if you have any questions. This is a combined synopsis/request for quote for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. Quotes are being requested and a written RFQ will not be issued. Shipping charges need to be included in price. The NAICS code is 423490. The specifications for the Liquid Chromatograph-Inductively Coupled Plasma/Mass Spectrometer (LC-ICP/MS) are as follows: Specifications Specifications for LC-ICP-MS System A Liquid Chromatograph-Inductively Coupled Plasma/Mass Spectrometer (LC-ICP/MS) system is required to be able to separate the elemental species in the ground water samples via a LC and to determine the elemental compositions by an ICP-MS. 1. LC system A LC system is required to perform the automated sample injection, separation and detection. 1.1 LC Pump A quaternary pump is required to ensure a pulse-free, stable solvent flow and efficient mixing of mobile phase solutions. A high-speed proportioning valve and a pre-configured vacuum degasser are required for convenient low-pressure mixing of four solvents and the flexibility in solvent pH choices. PEEK and/or PTFE tubing are required for the pump head. A seal wash feature for high salt mobile phases is also required. Flow range should be from 0.5 to 3 mL/min. The LC pump should also have a built-in leak and pressure test with graphical presentation of pressure profiles, and a maintenance feedback. The pump should be housed inside a compartment which can also house a module for two columns and at least four mobile phase solution bottles. At least four mobile phase solution bottles and the connections tubing are required. 1.2 Autosampler An LC autosampler is required to be able to inject a volume from 1 ?l to 1000 ?l. The autosampler should also be able to house over 60 sample vials of 1 to 2 ml size. The injection needle must be made of or coated with inert materials, in order to avoid direct contact of metal needle with samples. 1.3 Detector The LC system should be equipped with a variable wavelength detector (UV-visible). The detector should have high sensitivity and low detection limits with low baseline noise and drift. The detector should also be able to perform realtime chromatographic signal plot. 2. ICP-MS An ICP-MS is required to detect the elemental components of the chemical species that are separated and eluted from the LC column at trace and ultra-trace level. 2.1 Samples Introduction, ICP RF Power and Ion Optics The sample introduction system must allow the coupling of LC system as a sample introduction source besides the conventional sample introduction. The ICP RF generator must be a solid-state and have a high coupling efficiency so that reproducible analyses can be achieved through a high temperature and stable plasma. The sample introduction system should contain a quartz torch and a quartz spray chamber to allow the usage of MicroMist or PEEK MiraMist nebulizer. The spray chamber should be cooled constantly with materials such as Peltier. Ion optics should be designed to allow for analyses of high dissolved solids of up to 1000 mg/L of Na, K, Ca, Mg, and Cl. Proper vent duck kit should be supplied for proper heat and fume ventilation. 2.2 A Reaction Cell A reaction cell should be equipped with the ICP-MS to allow for simple collision or chemical reaction, so that the polyatomic interferences on critical elements such as arsenic, selenium, chromium can be eliminated. The reaction cell should not decrease the sensitivity of the above elements more than ten fold, comparing to the results obtained when the reaction cell is not used. Standard mode (no cell gas) should also be available to maintain a full capability of ICP-MS as a multi-element measurement technique. A gas purification kit should also be supplied, together with all the fittings and tubing required to connect the reaction cell with the reaction gas. 2.3 ICP-MS Detector It is required that the ICP-MS consists of a quadrupole mass analyzer. All the necessary vacuum pumps, connection tubing, and cable should be provided. The mass analyzer should be able to quantify elements from Li to U at sub ppb levels. For elements such as As, Be, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, Tl, V, and Zn, a detection limit of low ppt level is essential. The MS must be able to collect data at both pulse counting and analog mode. A calibration must be allowed to establish between the two data collecting modes. The dynamic range for quantification of elements should be at least 8 orders of magnitude. The instrument should also be stable enough for a drift of less than 10% for continuous calibration check during a ten-hour run. 2.4 Cooling System A chiller should be supplied to ensure the proper cooling of the ICP-MS. 2.5 PC and Computer Software A PC must be supplied to be fully capable of performing the task required by the instrument. A readable-writable CD drive must also be supplied, besides the normal floppy and CD drive. The instrument must be operated through user-friendly software. The software must be able to perform control and acquisition of ICP-MS. The software must also be able to be fully integrated into LC sequence control and data acquisition, such as collecting and analyzing chromatographic data in real-time. The software must be able to perform advanced peak integration routines, confirmation of target analytes and perform QC check. A quantitative analysis report should be able to print out automatically in real-time during the sequence, or the data can be manipulated (for example using different integration parameters) and quantified off-line later. Data must be able to be exported to Excel and manipulated into a different format. 3. LC-ICP-MS Connection Kit A LC-ICP-MS Connection Kit consists of all the components required to combine the LC with the ICP-MS. This includes all the necessary fittings, PFA tubing and cables for complete synchronization of the LC and ICP-MS. A connecting block which allows the column eluent to be directed into the standard nebulizer/spray chamber is also required. An additional internal standard must be allowed to be added post-column, for continuous point-by-point correction. 4. Arsenic Speciation Technology It is preferred that a LC column and eluent menu be provided for arsenic speciation and determination. The main arsenic species are arsenite, arsenate, monomethyl arsonic acid and dimethylarsinic acid. 5. In-house Modification 5.1 Electrical modification Depending on the instrument purchased, electrical wall plugs with specific configurations have to be installed to accommodate the instrument electrical features. 5.2 UPS System A UPS system is required to protect the ICP-MS from an occasional power outage. The specs of UPS will be provided depending on the type of instrument purchased. It is suggested that the UPS placed in Lab 305 (through the wall between lab 304 and 305), to minimize the heat depiction into Lab 304. 5.3 Ventilation System The fume and heat produced by the ICP-MS have to be vented outside the room. A ventilation modification is also required to accommodate the specific instrumental requirement. Detailed specs will be provided depending on the type(s) of instrument(s) purchased. 5.4 Reaction Cell Gas One or more gas cylinder(s) containing helium, hydrogen, or helium-hydrogen mixture, depending on the type(s) of instrument(s) purchased, need to be purchased to supply the reaction cell gas. The specs will be provided later, for the specific type(s) of instrument(s) purchased. 5.5 Argon Gas The existing manifold and tubing connection for argon gas in lab 304 has to be modified so that the new ICP-MS can draw Argon from the same liquid argon tank located outside Lab 304. 5.6 Gas Regulators Extra gas regulators, a single stage regulator in front of the instrument argon stream and one or more dual stage regulators (stainless steel, depending on the instrument purchased) for helium/hydrogen in front of the reaction cell needs to be purchased. 6. Lab Space Based on the relative clean environment required by the ICP-MS instrument, it is suggested that the ICP-MS be placed in Lab 304. All items shall be delivered to U.S. EPA, Robert S.
