There were no immediate issues or surprises, just a noticeable improvement in the overall consistency of our injections.
Extended Use & Reliability
After several months of consistent use, the Hamilton syringes have proven to be incredibly reliable. The build quality is evident; there are no signs of wear and tear on the syringe barrels or needle tips. Maintaining them is straightforward; a simple rinse with a suitable solvent after each batch of injections keeps them clean and prevents carryover.
Compared to our previous experiences with generic syringes, the Hamilton models have drastically reduced the need for recalibration and troubleshooting. The consistent injection volumes and robust needle design have significantly improved the accuracy and reproducibility of our analyses. These syringes have undoubtedly outperformed our expectations.
Breaking Down the Features of Hamilton Syringes for Agilent Technologies 7673A Autosampler, Hamilton 80391 Microliter Cemented Needle Syringes, Pack of 6
Specifications
-
Gauge: The 23S/26S needle gauge is a critical feature. The 23-gauge portion provides the necessary rigidity to penetrate the autosampler septum without bending, while the 26-gauge tip minimizes sample discrimination and allows for efficient on-column injections.
-
Volume, µL: The 10 µL volume is ideal for the typical injection volumes used in gas chromatography. This allows for concentrated samples to be used without overloading the column.
-
Hamilton No.: The 80391 part number ensures that you are getting the correct syringe specifically designed for the Agilent 7673A autosampler. This guarantees proper fit and function.
-
Unit: A pack of 6 ensures that you have spares available in case of damage or contamination, minimizing downtime in the lab. This provides a cost-effective solution.
These specifications are important because they directly affect the accuracy, precision, and reliability of the GC analysis. Using the correct syringe with the appropriate needle gauge and volume is crucial for obtaining accurate and reproducible results. Incorrect syringes can lead to peak distortion, inaccurate quantification, and even damage to the GC system.
Performance & Functionality
The Hamilton Syringes for Agilent Technologies 7673A Autosampler, Hamilton 80391 Microliter Cemented Needle Syringes, Pack of 6 perform exceptionally well in their intended role. They consistently deliver accurate and precise injection volumes, leading to improved reproducibility in our GC analyses. The syringes exhibit a smooth plunger action, ensuring that the sample is dispensed evenly and completely.
One of the main strengths is the robust needle design. The 23S/26S gauge needle prevents bending or coring, even with repeated use and when injecting into older, more worn septa. A potential weakness might be the fixed needle, which cannot be replaced if damaged, necessitating replacement of the entire syringe.
These syringes meet and exceed our expectations. They have addressed the inconsistency issues we were facing and significantly improved the overall quality of our GC data.
Design & Ergonomics
The Hamilton syringes are designed with a focus on functionality and durability. The stainless-steel construction feels solid and well-made.
