V2 Cigs, a pioneer in the electronic cigarette industry, is the first to provide its customers with electronic cigarette tests’ results for all their e-liquid tests. When a batch of cartridges comes off the production line, random cartridges are analyzed for the exact chemical composition and any contaminants, using state-of-the-art detection equipment by a certified third party tester (Skyte Testing Services Shenzhen Co., Ltd.). The cartridge e-liquid is analyzed for correct concentrations of Propylene Glycol/Glycerin and Nicotine, as well as tested for the presence of any dangerous contaminants:
- Diethylene Glycol
All V2 Cigs batteries and cartridges pass rigorous testing before being packaged and shipped to consumers. Every cartridge box has an expiration date and a batch number printed on it, which can be used to check the test results online using the V2 Cigs Batch Testing Page. See a Sample Test Report in adobe PDF format.
The tests are conducted using specialized testing methods and instruments: ICP-OES, GC-MS, GC-FID.
ICP-OES: Inductively Coupled Plasma – Optical Emission Spectrometry, is a method of analyzing the composition of a sample through emission spectroscopy, that uses inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. The intensity of this emission is indicative of the concentration of the element within the sample. ICP-OES is effective at detecting toxic elements such as lead, arsenic and mercury among many others.

GC-MS: Gas Chromatography – Mass Spectrometry, is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample. This is done by putting the sample gas through a stream of electrons, which will break the molecules into ions. The computer will then compare the mass to charge ratio of the sample ions to a library of data in order to determine which elements are present. This method can easily detect cancerous substances like Nitrosamines in e-cigarette e-liquid.
GC-FID: Gas Chromatography – Flame Ionization Detector, is yet another method to detect the presence of certain elements when they are burned. A GC-FID instrument functions by burning a sample gas with a hydrogen flame, then measuring the electrons emitted by burning carbon particles using a high voltage current. This type of detector can be used to identify the presence of Diethylene Glycol (the toxic kind of anti-freeze) inside electronic cigarette cartridges. Just one more reason why V2 Cigs is rated the #1 e-cig.
