LC-MS Ion Source Solution — Waters M951834CC1-S LockSpray Side Flange Assembly | Xevo & ACQUITY Series
Where This Product Is Used
The Waters M951834CC1-S LockSpray Side Flange Assembly is a precision ion source interface component designed for Waters LC-MS systems. It is deployed in environments where accurate, reproducible mass spectrometry data is critical:
- Pharmaceutical QC & R&D Labs — drug compound identification, metabolite profiling, and impurity analysis
- Environmental Testing Laboratories — trace contaminant detection in water, soil, and air samples
- Food Safety & Regulatory Testing — pesticide residue screening, mycotoxin analysis, and veterinary drug residue testing
- Clinical & Bioanalytical Research — biomarker discovery, proteomics, and pharmacokinetic studies
- Chemical & Petrochemical Analysis — polymer characterization and process monitoring
The LockSpray interface provides a dedicated reference compound channel that enables real-time mass accuracy correction, making this assembly essential for high-resolution accurate mass (HRAM) workflows on Waters Xevo G2-XS, Xevo G2-S, and SYNAPT platforms.

Application-Specific FAQ
Q: Which Waters instruments is this flange assembly compatible with?
A: This assembly is designed for Waters Xevo G2-XS QTof, Xevo G2-S QTof, SYNAPT G2-Si, and related ACQUITY-coupled LC-MS platforms that use the LockSpray ion source configuration. Confirm your instrument serial number with our team before ordering.
Q: Can this part be used to restore LockSpray mass accuracy after source contamination?
A: Yes. Replacing the side flange assembly is a standard corrective maintenance step when LockSpray reference signal is unstable or when source disassembly has caused seal degradation.
Q: Do you supply the full LockSpray source rebuild kit?
A: Yes. Contact us with your instrument model and we will compile a complete BOM quote including all consumable and semi-permanent source components.
Q: Is a Certificate of Conformance available?
A: Yes, CoC documentation is available upon request for regulated laboratory procurement requirements.
Q: What is the lead time for international orders?
A: Standard lead time is 3–7 business days. Expedited shipping via DHL Express is available for urgent instrument downtime situations.
