Injection split

WebbSplit injections are ideal for samples with high concentrations, high matrix loads, or when the limits of detection do not need to be low. The reason for that is that during … WebbOther problems, such as irreproducible injections, are more difficult to solve. Variable peak heights, split peaks, and broad peaks can be caused by incompletely filled sample loops, incompatibility of the injection solvent with the mobile phase, or poor sample solubility. Whenever possible, dissolve and inject samples in mobile phase.
