Time of Flight Mass Spectrometer (TOF MS)

• Stable long-term mass accuracy with a high-precision temperature control system that inhibits even tiny mass variations caused by external factors
• Achieves consistent mass accuracy values, even when samples are analyzed successively in both positive and negative ion modes; this significantly reduces the time required for stabilization and analysis for improved analytical throughput
• Fast, stable polarity switching through incorporation of proprietary high-precision electrical circuitry and the UFstabilization™ algorithm (patent pending)
• Ultrafast data acquisition rates
• Requires only a small sample size for identification of unknowns
• Auto-tuning function that uses a standard sample to automatically correct mass accuracy, resolution, sensitivity, and other parameters
• Easy maintenance; the desolvation line and the ESI capillary can be replaced quickly and easily without breaking vacuum, minimizing downtime

An affordable, robust option for routine sample analysis performed manually or automatically, the AXIMA Confidence offers reliable mass information and MS/MS-derived structural detail. A linear mode enables outstanding levels of analysis of high-molecular weight samples while the reflectron mode,

An affordable, robust option for routine sample analysis performed manually or automatically, the AXIMA Confidence offers reliable mass information and MS/MS-derived structural detail. A linear mode enables outstanding levels of analysis of high-molecular weight samples while the reflectron mode, incorporating the patented, newly improved curved-field reflectron, provides high resolution and mass accuracy.

Features:

High Sensitivity/Resolution
A variable repetition rate 50 Hz N2 laser and advanced ion optics for enhanced ion transmission enable users to meet all sample throughput requirements. Pulsed extraction of ions from the MALDI source, in combination with the unique reflectron design, improves resolution, and enhanced calibration algorithms with easy-to-use software provide more accurate data.

Easily Perform MS/MS
A seamless approach isolates ions of interest, and data-rich fragment ion spectra are quickly and simply acquired. The curved field reflectron design augments the low mass fragment region to provide additional information.

Positive and Negative Ion Modes Included as Standard
Allows greater flexibility and extends the compound categories that may be analyzed.

Patented Beam Blanker
Removes unwanted low mass ions and prevents detector saturation.

Unparalleled Flexibility
A variety of sample target formats, including standard microtiter plate format 96 or 384 well targets, can be used. In addition, Fleximass™ microscope slides (plain or 48 well targets) and a wide variety of adaptors for unconventional sample layouts are available.

Like all AXIMA MALDI-TOF systems, the AXIMA Confidence can be fully integrated with robotic sample preparation devices, including the AccuSpot MALDI plate spotter and CHIP chemical printer, to create application-specific platforms. Integration with the CHIP creates a powerful platform for tissue imaging, while using an AXIMA instrument with a Prominence GPC system and AccuSpot results in a fully automated platform for polymer analysis that delivers quick, detailed analysis of ultra-trace substances.
