A system embodiment includes a remote sampling system configured to collect a sample of phosphoric acid at a first location, the remote sampling system including a remote valve having a holding loop coupled thereto; and an analysis system configured for positioning at a second location remote from the first location, the analysis system coupled to the remote valve via a transfer line, the analysis system including an analysis device configured to determine a concentration of one or more components of the sample of phosphoric acid and including a sample pump at the second location configured to introduce the sample from the holding loop into the transfer line for analysis by the analysis device.

A sample introduction system provides mixing of a sample and a diluent within the container via gas injection. In one or more implementations, the sample introduction system causes a probe of an autosampler to be inserted into a container containing a sample and a diluent so that an end of the probe is submerged beneath a surface of the diluent and the sample. Gas is then injected through the probe to mix the sample and the diluent within the container. An aliquot of the mixed sample and diluent is then withdrawn through the probe.

Systems and methods for automatic preconcentration of fluid samples using alternating dual holding loops are described. A system embodiment includes, but is not limited to, a first sample loop and a second sample loop alternately fluidically coupled with a sample source; a first valve to alternately introduce fluid from the sample source to the first sample loop and the second sample loop; a second valve to alternately receive fluid from the first sample loop and the second sample loop and to alternately provide access to the preconcentration column to fluid received from the first sample loop and the second sample loop; and a pump system configured to alternately introduce sample held in the first sample loop and sample held in the second sample loop to the preconcentration column via the first valve and the second valve.
A capillary tube holder is provided for holding a capillary tube. The capillary tube holder includes a holder insert and a holder base. The holder insert includes a capillary groove configured for receiving the capillary tube. The holder base is configured for slidably receiving and retaining the holder insert therein.
