This is an aftermarket part, not an original manufacturer part. Instrument names and part numbers identify what it fits and replaces; they remain the trademarks of their owners. The manufacturer, country of origin, rated life and warranty are stated in the quote, before you decide anything. If you need the OEM part, say so and I will quote that instead.

Pump and injector spares

Metering syringe, 100 uL, for Thermo WPS-3000 autosamplers

Replaces OEM part number: 6822.0002

Metering syringe, 100 uL, for the WPS-3000, cross-referenced to 6822.0002. The syringe meters the injection, so its wear shows up as volume rather than pressure: areas that read low, or precision that falls off at small injection volumes while large ones still look acceptable. That is the tell, because a worn plunger loses a fixed volume and a fixed volume matters more when you are injecting 2 uL than 50. If your low volume methods have gone imprecise and your high volume ones have not, this is the part.

Before you order: if the instrument is misbehaving, tell me the symptom, not the part number. Lamps and seals get replaced for problems they did not cause. The first look costs nothing, and if this part is not the fix, I will say so.
