I-3202 semi automated Spotter

SES Model 3202 Spotter for TLC-FID techniques is a precision instrument specially developed for applying sample solutions onto the sintered silica gel surface of a ROD. The smaller and more concentrated the sample spot, the better the resolution obtained after development of the ROD in a TLC chamber. The reproducibility of quantitative and qualitative analyses with a TLC-FID Analyzer is closely related to the accurate application of a known quantity of sample onto the surface of a ROD in the form of a micro spot. With the "Autospotter" it is possible to apply between 0.020 and 5 micro liters of sample solution. The spotting is electronically controlled through a small external microprocessor module, with a precision of better than 0.5 %.
