Environmental Analysis World’s First Triple Quadrupole ICP-MS Launched
Agilent Technologies (USA) announces the launch of the Agilent 8800 triple quadrupole ICP-MS (ICP-QQQ), the first and only instrument of its kind. The new ICP-QQQ system offers improved performance compared to single quadrupole ICP-MS, and provides MS/MS operation for controlled and consistent interference removal in reaction mode. ICP-QQQ also addresses high-end application requirements, with flexible analysis capabilities unavailable on single quadrupole machines.
The unique QQQ configuration of the Agilent 8800 controls the ions that enter the collision/reaction cell, so the reaction conditions remain consistent and predictable even if the sample composition changes. The new instrument provides turnkey operation in a range of novel reaction modes, delivering effective and consistent interference removal for problematic elements in difficult samples. The Agilent 8800 can also be set up to operate like a single-quad ICP-MS, offering the security of replicating existing and familiar methodologies.
“Agilent’s 8800 ICP-QQQ retains the ease of use of a standard ICP-MS and provides better detection limits for phosphorus-containing and sulfur- containing compounds measured using LC-ICP-MS,” said Dr. Jorge Ruiz Encinar, department of physical and analytical chemistry, University of Oviedo, Spain.
The 8800 ICP-QQQ analyses problematic elements in samples across a range of applications, including; ultra-trace analysis of elements that suffer interferences in high-purity samples (Ge and As in HCl; V and Ti in H2SO4, and more), reliable low-level measurement of selenium and arsenic in
soil, rock and plant materials and where both polyatomic and doubly charged interferences may occur.
“The Agilent 8800 ICP-QQQ is a revolutionary new ICP-MS instrument, offering maximum flexibility for high-end research and for solving difficult analytical problems,” said Philip Binns, Agilent vice president for spectroscopy products. “The 8800 joins Agilent’s remarkable 7700 Series ICP-MS, which remains the benchmark for high-performance single-quadrupole ICP-MS. With the 8800, 7700 and recently introduced 4100 MP- AES as part of our portfolio, Agilent’s technology leadership in atomic spectroscopy is stronger than ever.”

Compound Based Scanning: Making the Transition From SQ to TQ GC-MS Easier
Bruker Chemical and Applied Markets (USA) have published in “Chromatography Techniques” a new article examining how Gas Chromatography (GC), coupled to a triple quadrupole Mass Spectrometer (GC-MS/MS-QqQ) operated in MRM mode, is rapidly becoming the preferred technique for multi-residue analysis in complex matrix samples by analytical laboratories.
Transferring from the single quadrupole to a triple quad can present potential difficulties for the chromatographer who may not necessarily be an expert in mass
spectrometry. Bruker has introduced an innovative user-friendly solution to this transfer with its proprietary Compound Based Scanning (CBS) software in the company’s new SCIONTM TQ system.
Major advantages of CBS is that the new work flow focuses on compounds and not each MRM. The MRM transition of an analyte does not need to be known by the user. Software auto-fills information from a factory installed read-only compound library that contains over 2,500 MRM transitions for more than 900 common contaminants. CBS then sets up the method and manages the TQ duty cycle during analysis and data acquisition. Compounds in the library are linked to retention time, primary and secondary MRM transitions, and collision energy. Using CBS dramatically reduces the time taken to set the initial MRM methods, improving workflow and productivity.
Analysis of pesticides in vegetable matrix using Bruker’s SCION TQ GC-MS/MS illustrates the use of CBS for developing an MRM based method to analyse 258 pesticides (516 MRMs) dramatically reducing the time taken to set the initial MRM methods for accurate data.

Spark-Free Cabinets with Explosion-Proof Interior
The latest guidelines for laboratories, BGR 120, state that interiors, in which dangerous, explosive atmospheres can develop, must be explosion-proof. These explosive atmospheres can, for example, be generated by flammable liquids which have been discarded.
Lovibond® spark-free cabinets from Tintometer (Germany) meet these requirements in full. Their interiors contain no sources of sparks and are therefore explosion-proof.
The cabinet temperature can be set continuously from +2°C to +10°C and is constantly controlled by a room thermostat. Defrosting is automatic and is electronically regulated. The structure is made up of steel panel housing with an impact-proof, bump-resistant powder paint coating. The interior is made of high-strength, durable plastic.
Lovibond® laboratory refrigerated cabinets are supplied in different sizes, offering capacities of 180, 260, 360 and 500 litres.

New Fully Automated Nitrogen and Protein Analyser
VELP Scientifica (Italy) presents the NDA 701 Dumas Nitrogen Analyser, extending its range of instruments dedicated to sample preparation and analysis in the food and feed industries.
The NDA 701 uses high-technology to optimise productivity. With the highest limits of detection and readability on the market and an RSD lower than 0.5% for EDTA, the user is assured of high precision results. Samples can be loaded in nearly 120 positions, using the same loading procedure whether solid, paste or liquid. Once loaded, the unit runs fully automatically offering exceptional reproducibility and comparability of results.
The DUMASoftTM software presents the program parameters, run conditions and results on a single
screen of your PC making operation quick and simple. Different calibration curves can be created and managed and an on-board database containing methods for numerous sample types and different nitrogen standards can be used to optimise analysis of specific samples. Data can be shown via on- board versatile reporting with output to a PC or LIMS in .xls, .txt or .csv formats for manipulation using the operator’s preferred software.
VELP Scientifica NDA 701 complies with all standards in the food and feed markets; AOAC, AACC, ASBC, OIV and ISO, making it an ideal choice for industrial and monitoring laboratories.
