In the packaging and printing industry, especially in the flexible packaging sector for food and pharmaceuticals that comes into direct contact with products, strict control of solvent residues is the lifeline for ensuring safety and compliance. Accurate detection of the purity and content of dozens of organic solvents, such as benzene, toluene, xylene, and ethyl acetate, has become an indispensable part of the industry chain. Addressing this demand for precision, Guangzhou Shounuo Scientific Instruments Co., Ltd. 's GC-05 gas chromatograph , as an outstanding representative of dedicated testing solutions for the domestic flexible packaging industry, is setting a new testing standard for the industry with its superior performance and high adaptability.
The GC-05 gas chromatograph is a professional-grade gas chromatograph , developed in strict accordance with and meeting multiple national and industry core standards, including Q/BT 2929, GB/T 10004, and YBB 00132002. It is widely applicable in packaging, food, pharmaceutical, new materials, chemical, and printing industries, with core functions addressing two key tasks: firstly, accurately detecting the overall solvent residue in packaging and printed materials; and secondly, accurately analyzing the purity and component content of various solvents. The instrument can efficiently separate and detect complex systems including benzene, cyclohexanone, xylene, ethanol, ethylbenzene, isopropanol, propanol, butanol, ethyl acetate, isopropyl acetate, n-butanol, toluene, n-butyl acetate, anilinephos, and 4-methyl-2-pentanone.
Its working principle relies on mature gas chromatography technology: using high-purity inert gas as the mobile phase, the components in the sample are efficiently separated in the chromatographic column due to differences in partition coefficients, and then enter a high-sensitivity detector (such as FID) to be converted into electrical signals. The intelligent workstation completes qualitative and quantitative analysis to ensure accurate and reliable results.
To address the challenges of testing flexible packaging, the GC-05 incorporates several industry-optimized features . Equipped with a 7-inch color intelligent touchscreen, the instrument offers intuitive operation and intelligent human-machine interaction. Its adjustable split/tailblowing function, combined with an advanced automatic rear-door column oven system and rapid programmed temperature rise capability, significantly improves testing accuracy and efficiency. The instrument boasts strong compatibility, allowing for flexible selection of various detectors and supporting connection to packed/capillary column injectors, automated liquid samplers, headspace samplers, and other devices to meet diverse analytical needs, from simple to complex.
In terms of reliability, the GC-05 features comprehensive self-diagnosis of faults and dual over-temperature protection, ensuring long-term stable operation. Its spacious column oven design facilitates the use of various chromatographic columns, expanding the analytical range. Furthermore, an advanced noise suppression system creates a quiet working environment, while the microcomputer control system achieves precise temperature control down to the 0.1°C level.
Key technical parameters demonstrate its strength: the detection limit of the flame hydrogen detector (FID) is ≤1×10⁻¹³g/s, with excellent baseline drift and noise control; the thermal conductivity detector (TCD) has high sensitivity, quantitative repeatability RSD≤1%; and the column oven temperature control range (room temperature +5℃～300℃) is wide, fully meeting the stringent detection requirements of relevant standards for trace residues.
The standard configuration includes the main unit, a dedicated chromatographic column, and necessary accessories. Users only need to provide their own computer, analytical alcohols, and nitrogen, hydrogen, and air sources (with a pressure reducing valve of 0.35–0.4 MPa required) to quickly set up a professional detection platform.
In conclusion, Guangzhou Shounuo Scientific Instruments Co., Ltd. 's GC-05 gas chromatograph is not only a high-performance gas chromatograph for plastic packaging , but also a complete solution for solvent residue. It integrates professional design, intelligent operation, and superior analytical performance, powerfully empowering companies in the packaging industry chain, ensuring product safety and compliance, and confidently meeting the quality requirements of domestic and international markets. It is a reliable choice for laboratory quality control.
