Scientific Stellar Mass Spectrometer

Key System Highlights

Improved ionization efficiency for more compounds at higher LC flow rates

Stellar MS is equipped with the Thermo Scientific OptaMax Plus Ion Source, which can provide higher evaporation temperatures for improved resolution and higher ionization capabilities.

Less time setting up the instrument, more time focusing on the science

The Stellar Mass Spectrometer features a built-in Auto-Ready ion source for on-demand or remote system calibrations without interrupting LC-MS system operation

Improved ion utilization through expanded capabilities of the new collision cell

The new collision cell is a curved ion concentration multipole (ICRM) that features both beam fragmentation (HCD) and precursor/product ion accumulation capabilities, which, controlled by dynamic automatic gain control (AGC), are released as ion packets to a linear ion trap at high pressure for subsequent manipulation or detection.

Efficient ion population management for fast and sensitive analysis

The hyperfast linear ion trap mass analyzer expands analytical capabilities while increasing fast, high-quality data acquisition.

Advanced Analytical Capabilities to Boost Lab Productivity

The high-pressure linear ion trap offers extensive ion packet processing capabilities, allowing multi-slot RF excitation for dissociation or ejection in SIM, higher-order MSn, SPS MS3, or Data Independent Acquisition (DIA) modes to address the most challenging quantitative experiments.

High sensitivity for single ion detection to meet the most challenging quantitation requirements.

Improved quantitative throughput across the range thanks to efficient and sensitive ion detection.

The dual-conversion dynode configuration coupled to the photomultiplier tube detects approximately 84% of trapped ions for single ion sensitivity.

Automated intelligence drives tMSn data acquisition

Streamlines tMSn method creation and data acquisition management. PRM Conductor software efficiently and effectively creates robust, targeted quantitative methods and manages reproducible data acquisition and processing.

Data Integrity with Adaptive RT Mode

The method uses a novel real-time mapping mode scheme to dynamically adjust time/scheduled data acquisition windows to tighter time intervals to eliminate missing values that compromise data quality.

Increase lab productivity with industry-leading polarity switching speeds

Reduce the time, cost, and challenges associated with creating and implementing highly multiplexed quantitative metabolic assays. Fast polarity switching speeds enable comprehensive combined acquisition of positive ESI and negative ESI information at all MSn levels on the LC time scale.

Eco-friendly dry pumps reduce energy consumption and maintenance.

Switching from two oil-filled front pumps to one dry pump reduces heat output by 22% and reduces maintenance needs.

Using a single dry pump also eliminates oil fumes and the need for oil checks and changes.
