Inquiry (采购产品): Colombia I work in Colombia, South America, and I need to calibrate some devices. These devices are used for natural gas detection level, so I need two blends in order to calibrate them: 1. I need 6,7 mg/m3 TBM (terbutyl mercaptan) 6,9 mg/m3 THT (tetrahydrothiophene) in Nitrogen (N2) 2. I need 20 mg/m3 THT (tetrahydrothiophene) in Nitrogen (N2) Could you manufacture these gases? If it is so, please let me know the prices, delivery time and expire date of them. I need 1 liter size cylinder aprox for each one. This is urgent.
