Real-World Testing: Putting Hamilton Syringes for Agilent Technologies 7673A Autosampler, Hamilton 87989 Microliter Cemented Needle Syringes, Pack of 6 to the Test
First Use Experience
I tested the Hamilton Syringes in our environmental analysis lab, focusing on the detection of volatile organic compounds (VOCs) in water samples. We ran a series of calibration standards followed by actual samples, monitoring peak areas and retention times closely. The consistency in peak area response was immediately noticeable, significantly reducing the need for repeat injections.
The syringes performed flawlessly across a range of temperatures in the lab, from a cool 18°C to a warmer 28°C. The plungers moved smoothly, and there were no signs of leakage, even with repeated use. The needles were sharp and easily pierced the autosampler septum.
The syringes were incredibly easy to integrate into our existing workflow. Simply load them into the autosampler carousel, program the injection parameters, and let the system run. Minimal user intervention was required.
Initially, I was concerned about the fragility of the glass barrels. However, the sturdy packaging and careful handling alleviated those concerns.
Extended Use & Reliability
After several months of continuous use, the Hamilton Syringes have maintained their initial level of performance. The accuracy and precision remain consistent, and there are no signs of degradation. They have become an indispensable part of our analytical process.
There’s been no wear and tear on the glass barrels, and the cemented needles remain firmly attached. Regular cleaning with appropriate solvents has kept them in excellent condition. One syringe experienced plunger damage due to accidental force, reinforcing the need for careful handling.
Maintaining these syringes is straightforward. We flush them with a suitable solvent (usually methanol or acetone) after each use to prevent carryover. This ensures that there is no cross-contamination between samples and prolongs the life of the syringe. Compared to previous syringes that required frequent replacement, these have proven to be significantly more reliable.
