Zinwi builds an instrument matrix to help upgrade the quality of e-liquid

With the development of the electronic cigarette industry in standardization and compliance, consumers' demand for the flavor and quality of e-liquid is also increasing daily. The e-liquid industry can only gain the trust and loyalty of consumers if it continues to pay attention to product quality. Since its establishment, Zinwi has been guided by quality and innovation to help the industry's high-quality development.

Behind the quality of Zinwi is the detection of every drop of high-quality e-liquid in the CNAS laboratory and the whole chain shaping system of the "People, Machine, Material, Method and Testing". Now, let us walk into those testing instruments closely related to quality and see how they can support high-quality e-liquid.

1. Instruments

Gas Chromatograph (GC)

Zinwi has 13 high-end gas chromatographs from Shimadzu and Agilent. The instrument is equipped with an FID detector, which has the characteristics of high sensitivity and wide linear range. It is mainly used in the detection of finished nicotine, PG, VG, and raw materials such as triacetin and arecoline.

Gas Chromatography Mass Spectrometry (GC-MS)

Zinwi has 10 gas chromatography-mass spectrometers of imported brands such as Shimadzu, Agilent, and Thermo Fisher. The instrument combines the strong separation ability of gas chromatography and the unique identification ability of mass spectrometry for unknown compounds, with high sensitivity and super ability to separate and detect complex compounds. These instruments are mainly used in the component analysis of e-liquid products, and the quantitative analysis of prohibited and restricted substances such as benzene series, 5 ketones, and 2 alcohols.

Headspace Sampler

The headspace sampler can be used as auxiliary test equipment, which can greatly reduce the detection limit.

Liquid Chromatography (HPLC)

Zinwi has 5 liquid chromatographs of imported brands such as Agilent and Waters. Equipped with DAD and RID detectors, the instrument has the characteristics of high separation efficiency, high selectivity, high detection sensitivity, and fast analysis speed. It is mainly used for prohibited and restricted raw materials such as aldehydes, ketones, sweeteners, pulegone, and vitamin E acetate. Analysis of matter.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

ICP-MS has high sensitivity and good selectivity and can measure multiple elements at the same time. It is mainly used in the testing of heavy metals in atomized liquid raw materials, research and development, and finished products.

Flashpoint Meter

The Flashpoint Meter focuses on testing the flash point of the product. It can measure the evaporation tendency of the substance and its stability after heating. It is an important indicator for the safety protection of the e-liquid product during transportation, storage, and use.

2. Production Environment Instruments

In order to ensure that the environment of the GMP production workshop meets the requirements of a 100,000-class clean workshop, we regularly monitor the purified water and workshop environment (settling bacteria, suspended particles, pressure difference, wind speed, air volume, temperature, and humidity), and regularly sample raw materials and products. Detection and control of total bacterial counts (e.g., E. coli, mold, and yeast).

Biochemical Incubator

It is used for the total number of bacterial colonies such as E. coli, mold and yeast.

Thermal Anemometer/Dust Particle Counter

Used in GMP workshop environmental testing to maintain a clean production environment.

UV Vis Spectrometer/Conductivity Meter

It is used for the test of production water to ensure the safety of production water.

3. Physical and Chemical Indicators Testing Equipment

In addition to the production environment, we pay attention to the physical and chemical indicators of e-liquid products and strive to create high-quality e-liquid products.

Through several years of insisting on the quality of the e-liquid, Zinwi Biotech has built an advanced high-end detection instrument matrix and a scientific and efficient detection system, with a complete detection team and a standardized detection process.

Zinwi will adhere to the mission of "Driven by Innovation, Exploring the Future", and is committed to creating high-quality, efficient delivery, and excellent flavor e-liquid solutions, leading the standardized development of the industry.
