The increased sensitivity of modern IR-Spectroscopy demands the highest purity solvents available. Our IR Solvents have undergone rigorous purification processes in order to ensure its suitability for IR-Spectroscopy. All IR-solvents are tested for the absence of foreign band absorption in the IR-spectrum (see Figure 1: IR spectrum of Carbon disulfide).
