- AN-RS-051Rapid detection of illegal adulterants in dietary supplements with Raman
Undeclared drugs in dietary supplements pose serious health risks. Metrohm’s SERS solutions enable fast, sensitive, on-site detection of adulterants without matrix interference
- AN-NIR-131Phân tích nhanh thức ăn thô xanh bằng Quang Phổ Cận Hồng
Quang phổ NIR cho phép phân tích nhanh chóng, đáng tin cậy các thông số chất lượng quan trọng trong thức ăn thô xanh từ cỏ linh lăng (ví dụ: protein, chất xơ và độ ẩm) mà không cần chuẩn bị mẫu.
- AN-NIR-100Ash determination in polyethylene
The standard test method for ash content analysis is thermogravimetric analysis (TGA). Although TGA is easy to perform, it is time-intensive and requires the use of nitrogen gas. In contrast to the primary method, near-infrared spectroscopy (NIRS) is a fast analytical technique which can measure multiple parameters including ash content in polymers within one minute.
- AN-NIR-123Flour analysis by near-infrared spectroscopy (NIRS)
NIR spectroscopy offers fast, chemical-free analysis of ash, protein, moisture, and rheological properties in flour – ideal for routine lab or atline quality control.
- AN_RA-010SERS detection of pesticides using screen-printed electrodes
EC-SERS enhances Raman sensitivity using electrochemically activated gold SPEs, enabling rapid, simplified pesticide detection without complex prep or instrumentation.
- AN-NIR-127Feed analysis with near-infrared spectroscopy (NIRS)
NIR spectroscopy enables fast, reagent-free analysis of fat, moisture, protein, fiber, ash, and starch in animal feed, streamlining quality control with no sample prep.
- AN-NIR-125Determination of olive oil quality parameters and adulteration with NIR spectroscopy
Near-infrared spectroscopy (NIRS) offers a fast, solvent-free alternative to traditional methods for assessing olive oil quality and detecting potential food fraud.
- EB-004Quang phổ cận hồng ngoại và Raman trong phân tích polymer: Giới thiệu tổng quan
