MDQ 1.2pgC/s

GB 31604.60-2024, residual solvent testing; the number of standard solvents has been increased to 25 items.

Accurately identify packaging material quality to ensure product shelf-life safety.

The IRXross has a spectral resolution of 0.25 cm⁻¹.

Determined according to the fourth method of the Determination of Packaging Materials by Infrared Spectroscopy (YBB00262004-2015); each layer shall be basically consistent with the reference spectrum.

Barrier property testing. The barrier properties of packaging materials affect the shelf life of food and pharmaceuticals.

0.05—100 g/d

Water vapor transmission rate is tested according to GB/T 26253; oxygen transmission rate is tested according to GB/T 19789.

Prevent heavy metal pollution (Pb, Hg, Cd, Cr, As, etc.) and the impact of oxidation reactions on the stability of contents.

The detection limit for three mercury species methods is 1.9~2.8 μg/kg.

GB 4806.7, GB 4806.13, GB 9685; Heavy metals (calculated as Pb), 4% (v/v) acetic acid (60 ℃, 2h) ≤ 1 mg/kg.

Ensure no interaction with food components via extract/immersion tests to guarantee packaging safety.

High-precision qualitative analysis; 04G CMS can obtain rich ion fragment information.

GB 4806.7-2023, GB 9685-2016, tested according to GB 4806.30-2016. Plasticizer content: the limit of quantification for diisononyl phthalate is 50.0 mg/kg; the limit of quantification for the other 17 phthalates is 5.00 mg/kg.

Analyze harmful substances in packaging materials that may migrate into contents to ensure the safety of contents.

Flow rate range of 1–5 mL/min.

According to GB 4806.7-2023, GB 4806.13-2023; tested by GB 31604.52-2021 method, the total migration of aromatic primary amines shall not be detected.
