In the essence, fragrance and daily chemical industry,Odor is not only the soul of a product, but also the core standard for measuring its quality, consistency, and safetyHowever, traditional sensory evaluation methods that rely on manual olfactory recognition are limited by strong subjectivity, fatigue, and difficulty in quantifying and inheriting standards; Although precision instrument analysis can analyze specific chemical components, it is difficult to directly relate complex overall sensory experiences and“Odor fingerprint”ThereforePEN3Electronic nose technology has emerged, providing a revolutionary solution based on its biomimetic olfactory principleIt simulates the biological olfactory system through a sensor array, which can quickly and objectively convert abstract odors into quantifiable digital signals, therebyAuthenticity identification of raw materials, monitoring of production process odors, research and development of new product fragrances, and evaluation of product stabilityBy waiting for key links in the entire industry chain, we have achieved“Experience driven”to“data-driven” A profound transformation.

Typical Applications

Raw material quality control and adulteration identification

The ingredients of natural spices (such as rose essential oil and sandalwood oil) are greatly affected by their place of origin and climate, and are expensive and easily adulterated.PEN3Can establish the scent of top-level raw materials“fingerprint”database Through comparative testing, it is possible to1-2Quickly determine within minutes whether the newly arrived raw materials meet the standards or have been diluted or adulterated with cheap synthetic products or other oils.

Production process monitoring and odor warning

In the production process of daily chemical products such as shampoo and skincare products, issues with raw materials, reaction processes, or equipment cleaning may introduce odors.PEN3It can be set at key nodes of the production line to monitor changes in volatile gases in real-time online. Once an abnormal odor pattern is detected, the system will immediately sound an alarm. Improve production stability.

New product development and fragrance analysis

For example, the smell of a successful perfume or popular daily chemical products“Decode”Analyze its overall odor profile to provide precise imitation or surpassing targets for independent research and development. At the same time, it can quantitatively evaluate the odor differences of different formula combinations, objectively judge the similarity between the new formula and the target odor, and greatly reduce the workload of perfumers and R&D personnel“Subjective blind testing”Frequency, accelerate the research and development cycle.

Finished product evaluation and stability testing

Shelf life prediction: Regularly detect the odor changes of products during accelerated aging or natural storage, predict their shelf life, and evaluate the effectiveness of the anti-corrosion system.

Packaging compatibility: Check whether packaging materials (such as plastic bottles and hoses) release odor molecules into the product.

Brand consistency: ensure that the basic odor characteristics of the same perfume or shampoo produced by different factories around the world are consistent.

advantage：

Objective Digitalization: Integrating Subjective Factors“pleasant-smelling”、“Stinky nose”Converted into objective sensor response spectra and data, the results are traceable and comparable.

Efficient and fast: Single analysis is usually conducted in1About minutes, far exceeding traditional gas chromatography-Mass spectrometer（GC-MS）Complex pre-processing and long-term analysis.

Easy to operate: No need for complex sample pretreatment, can be operated with simple training.
