LCMS-8050

Continuing the evolution of Shimadzu's UF technology，Shimadzu introduces the LCMS-8050 triple quadrupole mass spectrometer， offering unparalleled measurement speeds and high-sensitivity performance.

The high performance of the LCMS-8050 defes expectations， redefning high-sensitivity， high-speed analysis.

UFsensitivityTM

In order to improve desolvation effciency， the newly developed heated ESI probe combines a high-temperature gas with the nebulizer spray， assisting in the desolvation of large droplets and facilitating ionization. This development allows for high-sensitivity analysis of a wide range of target compounds.

UFswitchingTM

When performing simultaneous positive/negative ion measurements of multiple components， the proper acquisition of sharp UHPLC peaks depends on rapid polarity switching. The LCMS-8050 minimizes losses due to polarity switching and ensures the collection of suffcient data points for even the narrow peaks obtained with UHPLC， recording accurate peak shapes and allowing excellent reproducibility.

UFscanningTM

The LCMS-8050 is capable of simultaneously obtaining both qualitative and quantitative information in a single analysis. Acquisition occurs so rapidly that MS/MS scans and MRM measurements can be performed concurrently while maintaining quantitative accuracy. MS/MS scans are usable and reliable because even at 30，000 u/sec，Shimadzu uses a 0.1 u scan step.

UF-MRM

The LCMS-8050 is capable of simultaneously acquiring 555 MRM transitions per second while maintaining accuracy and precision. Suffcient data points can be collected for quantitation ions， reference ions， and internal standard ions even in chromatographic regions with unresolved peaks. The high sensitivity of the LCMS-8050 allows for trace-level analysis， such as pesticides in drinking water， without the need for sample preconcentration. This high sensitivity is maintained even when monitoring numerous MRM channels.

GCMS-TQ8040

The Shimadzu GCMS-TQ8040 is the frst triple quadrupole with Smart Productivity for high effciency sample throughput， Smart Operation for quick and easy method development， and Smart Performance for low detection limits and Scan/MRM.

These 3 smart technologies contribute to Smart MRM，and provide the most accurate， cost effective， and easy-touse triple quadrupole GCMS you have ever imagined.

Smart Productivity

Thanks to two new technologies， the GCMS-TQ8040 enables high-sensitivity， high-precision analyses， even in simultaneous analyses with more than 400 components. For the frst new technology， a new frmware protocol was introduced. As a result， data loading effciency is improved， enabling MRM analysis with up to 32，768 transitions in a single analysis. For the second， “Smart MRM” was newly incorporated into the software. This method creation function automatically sets the optimal measurement time for each component. Data is only acquired for the elution time for the target components，so more components can be analyzed simultaneously than with previous models， without compromising sensitivity even in multi-component simultaneous analyses.

Smart Operation

GC-MS/MS analysis requires multiple settings that can be confusing to the average operator. With Smart MRM， the GCMS-TQ8040 software sets the analytical conditions automatically， making method development painless， fast，and easy.

Smart Performance

The exceptionally effcient ion source and collision cell provide low detection limits. High speed scanning control （Advanced Scanning Speed Protocol， or ASSP）and simultaneous Scan/MRM analysis mode provides high quality library searchable fragmentation spectra， and accurate low-level quantitative data in a single analysis.

LCMS-IT-TOF

The LCMS-IT-TOF is a new type of mass spectrometer that combines QIT （ion trap） and TOF （time-of-f ight）technologies. When combining QIT and TOF， the greatest technological challenges were the eff cient introduction of ions into the QIT and the simultaneous ejection of trapped ions to the TOF. Here， we introduce the newly developed technologies used to solve these problems. The source design， desolvation capillary and reduced collision ion focusing Q-Array were adapted from Shimadzu's successful single-quad HPLC mass spectrometer. The Octapole Lens can introduce eluted ions from the LC to the ion trap by CII （Compressed Ion Injection） method eff ciently. The ion trap QIT gives an eff cient MSncapability with our new cleaning technology. In addition，BIE （Ballistic Ion Extraction） technology， provides high resolution/accuracy for all MS， MSn... modes. The temperature control of the f ight tube gives a mass stability with stabilizing the length of the ion f ight and ion acceleration voltage which affects the mass stability.

Dual-Stage Ref ectron gives an excellent resolution with optimizing energy absorption and time convergence.

High Resolution & High Precision in MSnMeasurement

The stable high-resolution spectra achieved throughout a wide mass range and high precision MSndata are derived from the DSR: Dual-Stage Ref ectron and the use of BIE: Ballistic Ion Extraction. These instrument advances can strongly assist in the use of MS for predicating accurate structural details.

High Throughput

Increased amounts of information are obtained for each measurement enabling much higher reliability in structural analysis. High-throughput analysis can be realized with the world's best performance hybrid MS used for structural analysis in terms of high-speed mass spectrum measurement and high-speed ion polarity switching.

High Sensitivity

High-Sensitivity detection of low concentration samples is derived through the use of Compressed Ion Injection（CII） within the ion optics， allowing for the ions to be placed eff ciently into the ion trap.

i-Series

With the i-Series and LabSolutions， Shimadzu offers a new relationship between operators and analytical instruments. The data acquired by i-Series featuring ICM （Interactive Communication Mode） is sent to the data center via the LabSolutions network and managed uniformly by a server. Confrm analytical results from your room. Use a smart device to monitor the current system status and chromatograms from anywhere in the facility.

Maximum Reliability

A 14-second injection cycle maximizes the number of samples that can be processed. Moreover， a total of 1536 samples can be accommodated in right and left sample racks. Excellent reproducibility for low injection volume less than 1 μL， wide range of linearity range and ultralow carryover （＜0.0025%） improve the reliability of data，especially for analyses of precious biological samples and direct analyses of concentrated samples.

Maximum Stability

The UV/VIS detector and the PDA detector employ dualtemperature control （TC-Optics and fow cell） and provide measurements with a stable baseline hardly affected by room temperature fuctuation. The Forced-air circulation method enhances column temperature stability. Maximum operating temperature of 85°C allows high-temperature analyses such as sugar analysis. Moreover， three 300 mm long columns or six 100 mm long columns can be accommodated.

Easier Operation

Uniform graphical user interfaces between system and workstation allow intuitive operations regardless of experience level and increase the operation availability of the i-Series. The browser functions in LabSolutions bring rapid processing of large amount of data， realtime statistical calculation and easy confrmation of anomalous values， enabling more effcient data processing.

Wealth Applications

Although it is an integrated LC system， the i-Series supports a wide range of applications according to your choice of detectors. Basic systems come with the choice of a UV-VIS detector or photodiode array （PDA）detector. You can add to this a fuorescence detector， a differential refractive index detector and a Evaporative Light Scattering Detector， as necessary. The innovative and superior performance of the i-Series supports your application requirements.

Smart Features

The i-Series saves lab operators time and energy. Combined with the LabSolutions automated functions， it reliably completes analyses under specifed procedures. In addition， the E-mail notifcation feature allows you to focus on other work， without worrying about analysis end time.
