SCIENCE & TECHNOLOGYnew and notable at ASMSCOMPANIES LAUNCH A VARIETY OF NEW INSTRUMENTSEarlier this month, more than 6,200 scientists gathered inDenver for the American Society for Mass Spectrometry’s59th Conference on Mass Spectrometry & Allied Topics. Atthe meeting, instrument companies unveiled an array of newproducts.MASS SPECTROMETERSAB SCIEX INTRODUCESION MOBILITYCAPABILITYAB Sciex is adding an extralevel of analytical selectivityto its Triple Quad 5500 andQTRAP 5500 instruments withdifferential ion mobility. In ionmobility, components in a mixtureare separated on the basisof molecular size and shaperather than mass, adding an orthogonalseparation method tothe instruments’ existing massbasedmethods. The SelexIONion mobility cell is incorporatedas part of the ionization source.AB Sciex customer Rick King,founder and director of PharmaCadenceAnalytical Services,said that adding SelexION to asystem improved the limits ofquantification by a factor of 10.BRUKER LAUNCHESCOMPACT VERSIONOF MAXISWith the new maXis impact,Bruker Daltonics istargeting labs that wantperformance but are alsowatching the bottom line.The new system achievesthe performance of theoriginal maXis with a smallerprice tag, not to mention ina smaller package. The newsystem is less than 2 meterstall, whereas the maXis isnearly 3 meters tall. ThemaXis impact achieves resolvingpower of 40,000 and 1-ppmmass accuracy for as many as50 full spectra per second. Withthe new instrument, Bruker istargeting the applied marketssuch as quality control and industriallabs.ORBITRAP FAMILY GROWSThermo Fisher Scientific announcedthree additions to theOrbitrap lineup. The OrbitrapElite (shown) is a high-fieldinstrument that increases thespeed and resolution of currentOrbitrap technology. Resolvingpower greater than 240,000can be achieved in a single onesecondscan. The high field andaccompanying performanceimprovements were achievedby shrinking the size of themass analyzer. At the lower endof the scale, the company introducedthe Q Exactive, a benchtopquadrupole-Orbitrap hybridsystem, which has increasedsensitivity and resolving powergreater than 140,000. The VelosPro is a dual-pressure ion trapwith improved speed and sensitivitythat can serve as a frontend for Orbitrap hybrid instruments.The system incorporatesa trap and a higher-energycollision dissociation (HCD)cell that can be combined withother dissociation methods.The Velos Pro can also operateas a stand-alone linear ion trapinstrument. Existing Velos systemscan be upgraded to thenew Velos Pro.WATERS EXPANDS MASSSPEC OFFERINGSWaters added new systems toits Synapt and Xevo families ofinstruments. The Synapt G2-Sincorporates the StepWaveion-transfer optics that thecompany first used in its XevoTQ-S. The StepWave’s off-axisdesign increases the efficiencyof ion transfer and helps eliminateneutral contaminants.Compared with previousgenerations of the Synapt,this system features 30-foldimprovement in signal intensity,fivefold improvement insignal-to-noise ratio, and 10-fold improvement in limits ofquantification. The Xevo TQD,Waters’ newest triple-quadrupolemass spectrometer, is anentry-level instrument aimedat routine quantitative analysis.The instrument featuresuniversal source architecturethat allows users to switcheasily between ionization methods.Data acquisition ratescan keep pace with the narrowpeaks in ultra-performance LCseparations.AXION PLATFORMDEBUTSPerkinElmer’s new AxION massspectrometry platform incorporatestime-of-flight MS with adirect sampling analysis source.This type of sampling relies onatmospheric pressure chemicalionization, thereby eliminatingthe need for sample prep. Userscan also choose electrosprayionization with interchangeablesnap-in probes that allow eachscientist to use his or her ownseparation and ionization probeon a shared instrument. Thatflexibility is expected to reducecross-contamination.COMPANIES INTRODUCENEW GC MASS SPECSAgilent and Thermo FisherScientific unveiled new gaschromatography-mass speccombos. Agilent’s 7200 Q-TOFcombines high resolution, accuratemass measurements,and tandem MS. The systemfeatures an ion source thatcan be removed, replaced,and running again in less than30 minutes. The company istargeting applications such asenvironmental analysis, sportsdoping, and energy research.Thermo introduced a new GCtriple-quadrupole MS, the TSQQuantum XLS Ultra. The systemincorporates the company’sHyperQuad technology, whichoffers high sensitivity as well asultrahigh selective selected reactionmonitoring for increasedselectivity.THERMO FISHER SCIENTIFICWWW.CEN-ONLINE.ORG 36 JUNE 20, 2011
AGILENT TECHNOLOGIESAGILENT ADDSION FUNNEL TOIMPROVED Q-TOFAdding an ion funnel tothe front end of the instrumentups the sensitivity ofAgilent’s Q-TOF LC/MS system.The 6550 iFunnel Q-TOF LC/MS system achieves femtogramsensitivity and acquisitionrates as fast as 50 spectra persecond. The ion funnel wasintroduced last year on a triplequadrupoleinstrument. NowAgilent has reengineered theion optics and electronics ofthe Q-TOF to accommodate theincreased ion flux.SEPARATIONS AND IONSOURCESEASY METHOD GETSEVEN EASIERIonSense unveiled the IDCube, a sample introductiondevice for the company’sdirect analysis inreal time (DART) ionizationmethod. The ID Cubestandardizes sample introductionfor synthetic chemists.The sample—either a powderor a dried liquid—is spotted ona mesh strip on a sample card.The user then slips the card intoa slot on the device, which properlyaligns the sample.WATERS INTRODUCESNEW UPLC SYSTEMWaters launched the new UPLCI-Class system. The instrumenthas reduced system volumecompared with the company’searlier systems. This smallervolume leads to decreased chromatographicdispersion, higherpeak capacity, and increasedresolution. This means thatcycle times can be shortenedwithout adversely affecting theseparation quality.SHIMADZU UNVEILSNEW AUTOSAMPLERShimadzu’s Nexera MP autosamplerfor the company’sultra-high-performance LCsystem has a seven-secondinjection time and a total cycletime of only 14 seconds. Followingeach injection, separatesolutions are used to rinse theneedle’s outer and inner surfaces,as well as the injection port.This extensive rinsing protocolreduces carryover to less than0.0015%. The autosampler accommodatesup to six microtiterplates.SOURCE FOR CETAKES OFFBeckman Coulter launchedthe CESI 8000, which incorporatescapillary electrophoreticseparation and electrosprayionization in the same module.The separation uses flow ratesas low as 10 nL/minute. Theelectrospray tip is filled witha conductive liquid that eliminatesthe need for a sheath flowthat might dilute the samples.The system results in improvedsensitivity and decreased ionsuppression.CELIA ARNAUD compiled and wrotethese product highlights.WWW.CEN-ONLINE.ORG 37 JUNE 20, 2011
