Technology I. Introduction When we analyze organic matter in complex samples, we usually use liquid-liquid extraction, solid phase extraction (SPE) and supercritical extraction (SFE).
technology. However, these methods have various degrees of defects, such as high cost, complicated operation, time-consuming and toxic organic solvents on the human body. United States
SUPELCO's SPME technology overcomes the shortcomings of previous traditional sample pretreatment techniques, which eliminate the need for solvents and complex devices and can be directly collected from liquid or gas samples.
Volatile and non-volatile compounds can be analyzed directly on GC, GC/MS and HPLC. Can be used with any type of gas and liquid chromatography, with manual and automatic injection

Revolution in sample pretreatment technology - solid phase microextraction (SPME) technology I. Introduction When we analyze organic matter in complex samples, we usually use liquid.
- Liquid extraction, solid phase extraction (SPE) and supercritical extraction (SFE). However, these methods have various defects, such as high cost, complicated operation, and time consuming.
Toxic organic solvents on the human body. The SPME technology introduced by SUPELCO in the United States overcomes the shortcomings of the traditional sample pretreatment technology, which does not require solvent and complexity.
A device that collects volatile and non-volatile compounds directly from liquid or gas samples and can be analyzed directly on GC, GC/MS and HPLC. Can be used with any type of gas phase
Used in combination with liquid chromatography, there are two types of manual and automatic injection. Second, the characteristics
Simple and fast set sampling, extraction, concentration, injection and integration 1. Simple: easy to operate, just press the handle. 2. Fast: can save 70% of sample pretreatment
between. 3. Economy: No need for solvents and syringes, each extraction head can be used more than 50 times. (up to about 200 times) 4. Non-toxic: because the solvent is not needed, the operator
The working environment of the staff has been improved, and the venom discharged from the laboratory has been reduced to a minimum to contribute to the environment in which we live. 5. Applicability: You can carry it with you.
Field sampling and direct injection on any model of GC and HPLE instruments.
