Replacing the ion transfer tube on a TSQ Quantum is a routine but critical hardware consumables decision. The tube bridges the atmosphere-to-vacuum gap in the atmospheric pressure ionization (API) source, and a capillary with the wrong inner diameter or length can degrade ion transmission. If you're shopping for a direct replacement, the Thermo Fisher 70111-20972 is a specific option to consider.
Quick Verdict
For a Thermo Scientific TSQ Quantum Access Max triple quadrupole, this sealed genuine ion transfer tube is a straightforward choice when you need a replacement. The part number is clearly identified as MPN 70111-20972, in new condition with original case. It's priced at USD 495.00.
Who It Suits
This consumable suits labs and service technicians maintaining a TSQ Quantum Access Max in need of a replacement ion transfer tube. It also fits buyers who prefer a Thermo Scientific part with clear part-number traceability. The country of origin is the United States.
What Stands Out From the Listed Details
This part comes sealed and genuine, in new condition with original case. The intended instrument is the TSQ Quantum Access Max Triple Quadrupole Mass Spectrometer, which removes the usual guessing about fit. The inner diameter is stated as 0.50 mm (500 microns) with a total length of 101 mm.
Meaningful Trade-Offs
The main limitation is specificity: this tube is engineered for the TSQ Quantum Access Max, not a universal capillary. If your instrument uses a different inlet configuration, you'd need to confirm the correct ID and length before purchase. The price of USD 495.00 is a notable investment for a single consumable, and the scope is the tube itself.
Bottom Line
For a TSQ Quantum Access Max owner seeking a Thermo Scientific ion transfer tube in new condition, this option at USD 495.00 is worth considering. Verify your instrument's exact source configuration before ordering.
