Hplc agilent

When evaluating Agilent HPLC systems (such as the 1100, 1200, 1260, or 1290 Infinity series), you must prioritize pump pressure limits (e.g., 600 bar for standard HPLC vs. 1300 bar for UHPLC) and flow rate accuracy (typically ±1%). Ensure the detector type (DAD, VWD, FLD, or RID) aligns with your specific analytes. For refurbished units, verify the maintenance logs and ensure the de-gasser and autosampler have been tested for precision and carry-over effects.

Ensure the system is compatible with OpenLab CDS or ChemStation software, and verify if the license is transferable. For regulated industries (pharmaceuticals/biotech), the system must support 21 CFR Part 11 compliance for electronic records and signatures. Request IQ/OQ/PQ (Installation, Operation, and Performance Qualification) documentation from the supplier to guarantee the equipment meets GLP/GMP standards.

Purchasing refurbished Agilent systems can reduce capital expenditure by 30% to 60%. However, you must factor in the Total Cost of Ownership (TCO), including the cost of consumables (columns, lamps, seals) and potential repairs. A reliable supplier on Made-in-China.com should provide a minimum 6-month to 1-year warranty on refurbished parts to ensure economic viability.

For routine QC (Quality Control), a standard Agilent 1260 Infinity II with a Quaternary pump is ideal due to its flexibility in solvent blending. For R&D or high-throughput screening, the 1290 Infinity II UHPLC is preferred for its speed and resolution. Always confirm the autosampler capacity (e.g., 100-vial tray) and whether a column compartment with temperature control is included for method stability.

The main risks include damage during transit and non-functional components upon arrival. Because HPLC systems contain sensitive optics and high-pressure pumps, you must insist on professional vacuum-sealed packaging and wooden crate crating. Use Trade Assurance services on Made-in-China.com to protect your payment until the equipment's arrival and initial power-on test.

Negotiate for an initial spare parts kit (including extra pistons, seals, and a D2 lamp) to be included in the FOB price. Demand a video factory inspection or a live demonstration of the specific unit's baseline stability test. Ask the supplier to provide remote technical installation guidance via video call to mitigate the lack of on-site engineers in your home country.

HPLC systems are classified under HS Code 902720. Ensure the supplier provides a Certificate of Origin to potentially reduce import tariffs under specific trade agreements. Due to the sensitivity of the equipment, Air Freight is highly recommended over Sea Freight to minimize vibration and humidity exposure. Ensure the shipment is covered by All-Risk Insurance.

Look for Audited Suppliers on Made-in-China.com who have undergone third-party verification by agencies like SGS or Intertek. Check their export history specifically for laboratory instrumentation and request customer references or case studies from previous international buyers to confirm their ability to handle complex electronic calibrations.
