Analysis of Acetaldehyde Content in Pharmaceutical Polyester Bottles by Headspace Gas Chromatography

Analysis of Acetaldehyde Content in Pharmaceutical Polyester Bottles by Headspace Gas ChromatographyThe PET polyester bottle acetaldehyde content detection instrument is suitable for plastic bottles for oral liquid preparations produced using injection molding technology with polyethylene terephthalate (PET) as the main raw material. This machine adopts a 7-inch touch screen LCD display, which dynamically displays graphics. This machine has optional configurations such as single gas injection system, dual gas injection system, automatic valve injection, etc. The interface protocol has been reserved for the system to facilitate docking.Main technical parameters：

Pressure protection method: The carrier gas has pressure protection function. When the gas pressure drops to 0.1mpa, the instrument automatically cuts off the power supply to effectively protect the safety of the chromatographic column.

FID has automatic ignition function, no need for manual ignition

Display mode: 7-inch touch LCD display

Temperature control area: 10 channels for temperature control, dual column box control channel

Temperature control accuracy: ± 0.1 ℃ - ± 0.2 ℃

Temperature control range: Room temperature ± 8 ℃ -450 ℃, with increments of 1 ℃

Program heating: 16 stage program heating, heating rate 0.1-40 ℃/min, with increments of 0.1 ℃,

Initial and termination time range: 0-6000min, with increments of 1min.

Automatic headspace samplerThe system pre stores a set of default analysis methods and allows users to store multiple sets of commonly used analysis methods and mixed run analysis methods for useThe keyboard can be used for * control.

Analysis of Acetaldehyde Content in Pharmaceutical Polyester Bottles by Headspace Gas Chromatography

Instrument features:fully automaticThe headspace sampler controls the chromatograph to achieve automatic operation, continuous analysis, unmanned operation, and high work efficiency.After each injection is completed, the system automatically uses inert gas to blow the sampling pipeline and quantitative ring to prevent cross contamination.The inert injection channel from the injection needle to the transfer pipeline isStandard configuration. Obtained the inertia of the injection system for *.From the sample to the instrument inlet, the entire system is heated to eliminate system cold spots, reduce sample peak broadening, and increase separation efficiency. Analyze the sampleOvertemperature and power outage protection, safe to use; The injection needle can be freely replaced
