Adequate liquidity was maintained in the interbank money market, as reflected by a high average daily transaction volume totalling Rp18.96 trillion, which helped to sustain low overnight interbank rate volatility.
Separation was obtained using a LiChrospher 100 RP18, 5 mm, 4x250 mm (Teknokroma, Barcelona, Spain).
(11) The mobile-phase was acetonitrile:phosphate buffer pH 3.0 (40:60 v/v) at a flow of 1mL/min and the column was an RP18, 150 mm x 4.5 mm (Perkin Elmer) at 30 [degrees]C.
Fine-earth textures are according to WRB: HC - heavy clay, CL - clay loam, SiC - silty clay, SCL - sandy clay loam, L - loam, LS - loamy sand, S - sand Location Horizon >0.063 (%) <0.002 0.002-0.063 Soil textture (%) (%) AK A 41.7 25.8 32.5 L AK Bwl 53.9 19 27.1 SL AK Cl 12.6 14 73.4 HC PP1 A 45.5 23.8 30.7 L PP1 El 52.6 23 24.4 CL PP1 Cl 9.1 40.7 50.3 SiC PP2 A 53.9 20 26.2 SCL PP2 E 88.8 4.3 6.9 LS PP2 Cl 39.9 30.4 29.8 CL PP3 A 39.5 19.7 40.8 L PP3 B 83.3 7.6 9.1 LS PP3 C 47.7 11.7 40.5 L PP12 A 33.5 34.4 32.1 CL PP12 BCl 56.5 15.8 27.7 SL PP12 Cl 72.1 6 22 SL RP14 AH 28.2 38.3 33.6 CL RP14 Bl 30.4 36.9 32.6 CL RP14 Cl 26.6 31.6 41.8 CL RP18 AH 75.5 14.2 10.3 SL RP18 C 94 1.7 4.4 S Table 2.
Analyses were performed using Luna RP18 column (250x4.6mm, 5 [micro]m, Phenomenex, USA) and an Agilent 1260 Infinity (Agilent Technologies, Germany) equipped with G1314B UV detector, G1311C quaternary gradient pump, and G1329B autosampler.
HPLC methods developed for RHT commonly employ a buffer in the mobile phase and special columns, such as Kromasil [C.sub.8], XTerra RP18, and 5[C.sub.18]-MS, with either UV or fluorescence detection for the analysis of RHT in different samples [14-17, 26-29].
The separation was carried out with a Column C18 25 x 0.46 mm (Teknokroma Professional Friendly Lichrospher 100 RP18 5 [micro]M, 25 x 0.46, serial number NF-21378, Barcelona, Spain), using a gradient elution at a flow rate of 1 mL per min for 30 min.
Chromatographic analyses were performed by Waters 2695 series HPLC System (Milford, MA, USA); chromatographic separation was achieved by Waters XTerra RP18 (2.1 mm x 150 mm, 5 [micro]m) analytical column.
The column used was an Acquity UPLC[R] BEH shield RP18 1.7 [micro]m, 2.1 x 100 mm.
capillaris was separated using a RP18 column with a gradient of [H.sub.2]O-MeOH (60 : 40 v/v) for 50 min and then changed to 0 : 100 for 20 min to yield compound 1 (2 mg).
Auto sampler was used to inject 20 [micro]l of derivatized samples into column (Neucleosil[R]: RP18, 5 [micro]m, 4.6 x 250, 30[degrees]C).
