Product Introduction
Edible-oil operations need a practical way to separate routine screening from the confirmation path. SHJ-T1 supports this front-end decision in a card-based fluorescence quantitative immunochromatographic workflow. Treated sample is applied to the card; antigen-antibody binding generates fluorescent complexes; the instrument excites the signal and uses its preset curve to report plasticizer content. For peanut, soybean, rapeseed and blended oils, this gives inspection and quality teams a documented rapid-screening point before their defined escalation process. The configuration is built around 10.1-inch interface and supplied 8-well incubator.
Applications
- Incoming oil control: supports a screening checkpoint before material release.
- Production quality control: provides a structured read-and-record step.
- Supervision work: supports surveillance and risk-monitoring workflows.
- Third-party pre-screening: helps triage samples before confirmation.

FAQ
Can it replace a confirmatory method?No. It is designed for rapid screening; maintain a documented confirmation path where a decision requires it.
Which oils are stated?Peanut oil, soybean oil, rapeseed oil and blended oil are identified. Other matrices need reagent confirmation.
What are the stated range and quantification limit?0.1–20.0 mg/kg (ppm) and 0.3 mg/kg (ppm), respectively.
How should the three models be selected?Choose SHJ-S for portable work, SHJ-T1 for a single-channel desktop process with supplied 8-well incubator, or SHJ-T6 for six integrated channels.
