“…However, it must be considered that not all commercial apparatuses can be used because, due to bubble formations during runs, an external pressure (10–12 bar) is necessary. Although some examples of gradient elution by CEC have been reported, with the common used instrumentation, this experimental mode is a bit difficult .…”

“…Much focus has been on finding efficient methodologies for the separation of such species from various environmental and biological matrixes. Also CEC‐MS studies have been developed for the analysis of PAHs, and four differing monolithic materials have been employed: silica , sol‐gel photopolymerization‐based methacryl‐oxypropyl‐trimethoxysilane (MPTMS) , hexylacrylate , and poly(stearylmethacrylate– divinylbenzene) (poly(SMA‐DVB)) monoliths. Since ionization with ESI for nonpolar PAHs is inefficient, API techniques have been utilized in these studies.…”

“…Although there are no principal restrictions to interface CEC to APCI‐MS, only few information is available on the combination of these techniques. This is possibly because no commercial APCI interfaces are available for CEC and the difficulty in combining a packed capillary column to MS interface because of the poor reproducibility in the fabrication of the frit inside the capillary . Norton et al.…”

“…Cheng et al. developed a CEC–APCI‐MS technique for the determination of 16 PAHs in seafood samples with as low as 10–50 ng/g level by a simple normal injection or on‐line preconcentration mode.…”
