Instrument Introduction

Teledyne Tekmar launched commercial blow and capture products as early as 1976, and has now become synonymous with innovative and high-quality products in the field of VOC (volatile organic compound) analysis, widely used in industries such as pharmaceuticals, environment, food, and materials.

Lumin volatile organic compound analyzercarryThe newly developed capture trap can provide capture performance, and the excellent mass flow controller (MFC) can transport gas. In addition, when paired with AQUATek 100 liquid automatic sampler, it can greatly improve the analysis efficiency of the laboratory.

Lumin volatile organic compound analyzermain features

1. Add protective panels to effectively protect the safety of the blowing pipes and operators;
2. Mass flow controller (MFC) can control the flow rate of carrier gas;
3. Inert sample transfer pipelines can effectively reduce sample residue;
4. The new dehumidification system has strong water removal effect;
5. The trapping tube packing provides excellent adsorption/desorption efficiency;
6. The rearrangement of the cooling fan effectively improves the cooling rate;
7. The optimized design of the capture trap facilitates the replacement of the capture tube and makes maintenance easier;
8. Enhance foam monitoring and elimination functions to protect equipment from pollution;
9. Simplified color categories for status indicator lights, making the working status clear at a glance;
10. Abandoning traditional RS232 data interface and adopting USB interface to improve data transmission speed and stability;
11. The software has powerful diagnostic and self checking functions, and can be used more reasonably in conjunction with GC/GCMS software.

Volatile environmental sampling
At room temperature, the properties of VOCs cause these compounds to vaporize, evaporate, or sublime from liquid or solid form, thereby allowing them to enter the atmosphere. The design of sampling methods and extraction techniques must ensure that volatile losses are limited from collection to analysis. Similar to SVOC analysis, the type of sample being analyzed determines the required extraction method. However, the technology for capturing and separating VOCs is completely different from semi volatile methods.

Headspace technology for VOC analysis

In a sample bottle, the unoccupied area above the sample is usually referred to as the headspace. Using the static headspace method, it is necessary to slightly heat the sealed vial containing the sample to transfer the VOC compounds from the sample matrix to achieve gas phase equilibrium. After reaching steady state, collect the gas phase inside the small bottle or transfer it directly to the instrument for analysis. This technique is typically applicable to compounds with relatively high Henry's law constants. However, this method may not be applicable to MTBE or ethylene dibromide (EDB).
