如何查找COA批号
批号可以在产品标签上"批“ (Lot或Batch)字后面找到。
如果您查询到的批号为 TO09019TO 等,请输入去除前两位字母的批号:09019TO。
如果您查询到的批号含有填充代码(例如05427ES-021),请输入去除填充代码-021的批号:05427ES。
如果您查询到的批号含有填充代码(例如 STBB0728K9),请输入去除填充代码K9的批号:STBB0728。

Many consider the traditional Thermogreen LB-2 septa as the benchmark for low bleed GC septa. Rubber formulation exclusive to Supelco "Often mimicked, never duplicated" Now, the best septa formulation is offered in a molded design.
Every septum conforms to the same mold shape with crisp, clean sides, resulting in easier installation and better sealing.
These septa have several benefits.· The exclusive rubber formulation provides ultra low bleed over a wide range of inlet temperatures (100 °C to 350 °C).· No foreign substances or powders (which could contaminate the inlet) are used during manufacturing.· All septa are fully tested for bleed and contamination.· All septa are pre-conditioned, therefore, they are ready to use.· They are ideal for use with low bleed GC-MS columns.
The versions are designed as follows:· The version with an injection hole is designed for customers who use autosamplers. This version is also suited for users of solid phase microextraction (SPME).o A dimpled center guides the needle through the septa.o Allows needle penetration through the same location, time after time.o Reduces septum coring, preventing septum fragments from entering the injection port.o Have a high puncture tolerance and long life.· The version without an injection hole is designed for customers who do not use autosamplers.
Yes. These are superior in all areas to die-cut septa as well as molded septa from other manufacturers.
Higher temperature does not relate to higher quality when discussing GC septa.· To make septa with a higher temperature, they need to be stiffer. This makes them harder to puncture, resulting in shorter life.· GC users typically do not use an injection port temperature above 350 °C. We choose to make softer septa that result in easier penetration, less coring, and long life.

Bisphenol A (BPA) plastic is controversial in food and beverage containers. This study demonstrates SPME of BPA from an energy drink using an overcoated PDMS/DVB fiber, followed by GC/MS/MS analysis using SLB-PAHms GC Column.
Terpenes are present in essential oils derived from plants and often impart characteristic aromas to the plant or its oil. The SPME is a convenient, efficient, and easy to automate sample preparation technology for analyzing the terpene/terpenoid profile of these plant materials.
Bisphenol A (BPA) is suspected to be an endocrine disruptor. Regulations on specific migration limits (SML) from food contact materials are getting tighter (EU 2018/213) requiring more sensitive determinations. An overcoated SPME fiber provides the durability necessary for direct immersion into foods such as canned soup and pumpkin, allowing for low level analysis of BPA via SPME-GC-MS/MS.
The use of solid phase microextraction (SPME) allowed for the straightforward, fast, sensitive, and accurate GC/MS determination of the residual solvent content of spiked and unspiked samples of hemp extract.
