Thermo Scientific Prima BT Bench top Mass Spectrometer

• ​Ion Source: Enclosed Electron Impact with Dual Filaments, temperature controlled (settable over range 120-200 degrees C, to ± 0.1 degrees C)
• ​Analyzer Type: Scanning Laminated Electromagnet, 6 cm radius, 80 degrees deflection
• ​Mass Range: Adjustable, default is 1-150 amu at 1000 eV ion acceleration voltage, (at 750 eV ion acceleration voltage, mass range is 1-200 amu)
• ​Resolution: Switchable between two collector resolving slits, resolving powers of 60 (1mm) and 20 (4 mm) are standard. Optionally 140/85 (0.36 mm/0.69 mm) or 100/45 (0.56 mm/1.45 mm) or 140/45 (0.36 mm/1.45 mm) may be fitted
• Mass Scale: Stability Measured at mass 28 < 0.013 amu over 24 hours
• ​​Peak Shape: At 60 resolution, the ratio of the width of the flat-top (99% height width) to the base peak width (5% height width) 0.5
• ​Abundance Sensitivity: <250 ppm for 27/28 amu
• ​Detector: Faraday and optional Faraday/SEM dual detector
• Inlet: Temperature controlled micro-capillary with Molecular leak and bypass (standard configuration)
• Vacuum System: Turbo-molecular Pump and external Rotary Pump Alternatively Turbo-molecular Pump and internal diaphragm pump
• ​Sample Flow: Digitally measured and recorded for each stream for any instrument with RMS option
• Precision: <0.1% relative (typical, application dependent) external rotary pump
• Linearity: <1% relative over a decade change in concentration (typical, application dependent)
• Dynamic Range: 10 ppb – 100% (theoretical, application dependent) external rotary pump only
• Stability: <1% relative over 1 week (typical, application dependent)
• Power Requirements 115 Vac (±5Vac) or 230 Vac (±10 Vac)
• ​Physical Dimensions 52cm (20.5”) H x 79cm (31.1”) W x 47cm (18.5”) D 100 kg (200lbs) configuration dependent
