Maintenance Kit for Auto Sampler
This kit includes:
Maintenance and replacement:
- Plastic Needles: Replace the plastic needles regularly if your lab frequently uses the autosampler, especially if you're working with corrosive or viscous samples that can wear out the needles more quickly. Replace immediately if you notice any damage, such as bending, cracks, or erosion of the needle tip. Even slight deformities can lead to inaccurate sample aspiration or contamination. If the needle becomes blocked or if cleaning does not restore its function, it should be replaced to ensure accurate and consistent sampling.
- Drive COG: Inspect the drive cog periodically for wear, such as teeth that have become rounded or broken. If the cog is damaged, it can cause the autosampler to misalign or fail to move correctly. Unusual noises, such as grinding or skipping sounds during operation, can indicate a worn drive cog that needs replacement.
- Belt Arm (X, Y, Z): Replace the belts if you notice signs of wear such as fraying, cracks, or stretching. Any visible damage can cause slippage or misalignment of the autosampler’s movements. If the belts lose tension and become loose, they can cause inaccurate positioning of the sample probe, leading to incorrect sample delivery. If the autosampler fails to move along any of the X, Y, or Z axes properly, or if you notice inconsistent movement, it could be a sign that the corresponding belt needs replacement.
- Capillary: If the capillary becomes blocked and cleaning does not restore proper flow, it must be replaced. Blockages can lead to inaccurate sample delivery or instrument errors. Capillaries are prone to wear over time, especially if exposed to aggressive solvents or abrasive particles in samples. Replace them if they show signs of wear, such as thinning or cracking. If the autosampler is delivering inconsistent sample volumes or if there's a drop in analytical performance, the capillary might be compromised and should be replaced.
