Dip plates

Rhodamine 6G (0.1 g l-1 in water) Spray or dip plate and view under UV light A versatile stain for all lipid classes. Pink-purple-red spots. Most useful with alkaline solvents. The dye may be incorporated in the plate... 

Spraying/dipping plates 12345 pp. 43-45 Plate dipped with Dragendorff s spray yields similar result to the one sprayed with the same detection reagent. 

Ninhydrin, 0.2% (w/v), is dissolved in ethanol and stored in a refrigerator. Just prior to use, 0.5 ml of 2,4,6-collidine is added to each 50 ml of the ninhydrin solution. Color development can be hastened by heating the dipped plate with a warm air gun. This reagent gives distinctive colors for a large number of amino acids (Table 2). 

Figure 87a,b shows the dipped plates in solvent mixtures 1 and 2 and Fig. 87c the scanned chromatogram of polidocanol in solvent mixture 2. 

Bile acids can be also detected by dipping plates into 10% of phosphomolybdic acid in ethanol and then heating for 20 min at 120X" or by spraying the plates with a 1% solution of phosphomolybdic acid in 2-propanol and then heating at 120°C for 5-10 min.

Palladium chloride detects phosmethylan (55) with 0.5 pg/spot sensitivity. This reaction was used for quinalphos (7), phosphamide (8), and methamidophos in food samples (154) as well. Malathion residues were studied in pharmaceutical preparations by dipping plates into a 0.1 % solution of palladium chloride in hydrochloric acid, yielding yellow spots that could be quantitatively determined by scanning at 400 nm (159).

B. As A, but buffered by dipping plate into 0.2 M ammonium sulfate and allowing excess liquid to drip off plate... 

Figure 11.6 Simulation result of gas entrainment in large-scale test (a) stream line around H/L and C/L and (b) trajectory of entrained bubble. H/L, hot leg C/L, cold leg D/P, dipped plate.

Depositing a metallic coating on a metal immersed in a liquid solution, without the aid of an external electric current. Also called dip plating. 

Hoping to reduce lead exposure, the bank bought copper dip-plated lead target bullets and NIOSH sampled the air again in April 1987.
