In the field of LC-MS analytical applications, achieving optimal separation and sensitivity is a challenge. Many research laboratories invest in modern mass spectrometry instruments, but often neglect the importance of components like the chromatography column and emitter. Traditional column designs have inefficiencies, including pre-column and post-column dead volumes, which affect separation efficiency and cause peak dispersion. These inefficiencies can impact analytical precision, prolong analysis time, and increase operational costs. The IonOpticks’ pulled emitter column integrates nano-flow sensitivity with analytical flow chromatography reliability. The unique NanoZero column connection fitting reduces the pre-column dead volume where voltage is applied, improving separation efficiency. The columns utilize a monodisperse reversed phase material with optimized pore geometry. The fabrication techniques used ensure the packed emitters are reproducible and robust, providing consistent spray stability and longer operational life. Historically, the success rate of fabricating packed emitter columns has been less than 20%, limiting their widespread use. Improvements in manufacturing techniques have addressed this limitation, enabling more researchers to access high-performance chromatographic tools. The aim is to make high efficiency, sensitivity, and reliability more accessible to the wider scientific community.
