The Agilent QTOF 6540 is an accurate mass MSMS instrument based upon quadrupole and time-of-flight technology. The instrument accommodates several different solution-based atmospheric pressure ionization sources including electrospray (ESI), chemical ionization (APCI), and JetStream ESI. The instrument can acquire data in positive or negative ion mode, MS, or MS/MS mode. Agilent MassHunter software is used for data acquisition and data processing. The software package includes modules for determining elemental composition, molecular feature extractor, deconvolution, et cetera.

Working Mode of Agilent 6540 Q-TOF Mass Spectrometer
TOF Mode

The Quadrupole is under the situation of Total Transmission Ion (TTI), which means all ions can pass the quadrupole. The collision cell does not fragment the ions and works as ion transmission devices. The TOF mass analyzer is in the scan mode and can directly detect the ions. The mass spectrum obtained from the TOF mode is equivalent to the one from the single TOF mass analyzer.

Auto MS/MS Mode

In this mode, the instrument can automatically perform secondary mass spectrometry on qualified ions according to the conditions set by users. When a particular ion or a set of ions meet the set conditions, the quadrupole is in the selected ion monitoring (SIM), and the collision cell can fragment ions. Then the fragment ions can be scanned by TOF and get a mass spectrum. The auto MS/MS mode is commonly used for unknown compounds identification and structure analysis.

Targeted MS/MS Mode

In this mode, only the ions targeted by users can get mass spectrum. Similar to the auto MS/MS mode, the quadrupole is in SIM, and the collision cell can fragment ions. Then the fragment ions can be scanned by TOF and get a mass spectrum. This mode is useful for the quantitative analysis, identification of known compounds, and structural elucidation.

LC pumps can handle up to 8000 psi
MS and MS/MS on the fly
Mass Range of up to 10,000 Daltons (singly-charged)

Quality

Our refurbished instruments are tested and repaired to meet factory specifications. We follow Installation Qualification, Operational Qualification, and Performance Qualification protocols (IQ, PQ and OQ).

Expertise

Our team of skilled technicians are experts at fixing analytical instruments. We have been working with Agilent, Waters, Perkin Elmer, Sciex, Shimadzu, and Thermo instruments for many years. We are constantly updating our knowledge with the latest technology and information to enable us to deliver the best support in the industry. We provide value added support and qualification/validation with all our instruments. We endeavor to develop strategic partnerships with our clients so that they consider our team as an extension of their employees. We are an affordable alternative to many normally expensive business projects.

Warranty and Support

We offer warranty on all refurbished instruments. Warranty starts at 3 months, with the option to extend the period. While your instrument is on warranty, we will provide Email (support@spectralabsci.com) and phone support and troubleshooting if you require assistance. If there is ever anything wrong with the equipment, we will replace it. Warranty begins from the date your equipment is successfully delivered. Any issues that occur during warranty should be reported immediately, describing the issues in as much detail as possible. Do not attempt to repair the equipment or involve a 3rd party without our express permission – this will result in voiding our warranty.

We will match our warranty duration with our competitors.

Installation and Training

If you purchase equipment from Spectralab Scientific, we offer installation and familiarization by our service technicians for an additional fee. If the instrument is particularly complicated, we highly recommend this service. If you’ve purchased less-complex equipment from us that you would like to install yourself, we can provide Team Viewer, email, or telephone support for no additional cost.

Large Inventory

We have a large inventory of equipment, components and parts in stock. You can find all the equipment you need for you lab in our store, as well as mix and match components for your systems.

International Shipping

We have sufficient export experience, including professional packing and proper documentation. Complementary shipping and handling can be applied upon immediate purchase. We include customs fees, brokerage, and duties for shipping to the US.

Price Matching & Discounts

Purchasing our refurbished instruments can save you anywhere from 30% to 90% compared to purchasing brand new. We will try to match or beat any price from our competitors, so feel free to inquire! Complementary shipping and handling can be applied upon immediate purchase.
