The at-risk FFAP
level would be 65% in 2008, 70% in 2009 and 75% in 2010, officials write.
A 25 m(FFAP
) capillary column was used during chromatographic separation.
Still, in 1982, an attempt was made to repair some of the damage when the State instituted its Full Freight Access Plan (FFAP).
Absolutely essential to the success of the FFAP, however, was the construction of an intermodal freight transfer center within the City.
The VFAs determination was performed using gas chromatography (SP-6800A, Shandong Lunan Instrument Factory, China) equipped with a flame ionization detector and a FFAP
capillary column (30 mx0.32 mmx0.50 mm, Lanzhou ZhongKeKaiDi Chemical New-tech Co., Ltd, China).
The VFA contents of cultured fluid were determined using a gas chromatograph with a semi-capillary FFAP
column (Hewlett-Packard, Wardbronn, Germany), over a temperature range of 45-230oC.
They were prepared following the procedure developed by Thies (1971), and analysed on a Perkin Elmer gas chromatograph model 8600 (Perkin Elmer Corporation, Norwalk, CT, USA) equipped with a fused silica capillary column FFAP
, 25 m 0.25 mm 0.25 m film thickness (Macherey & Nagel GmbH + Co.
The total volatile fatty acid (VFA) in samples of supernatant fluid were measured by a gas chromatograph (Hewlett Packard 6890, USA), (column temperature: 120[degrees]C, injector temperature: 265[degrees]C, detector temperature: 240[degrees]C) equipped with an autosampler and closslinked polyethylene glycol, o0.53 mmx30 m size FFAP
column (Hewlett Packard, USA).
Samples for VFA analysis were prepared as described by Li and Meng (2006), and VFA concentrations were determined using gas chromatography (GC-2010, Shimadzu, Japan) with a 30 m FFAP
capillary column (0.25 mm i.d.
VFA in samples of supernatant fluid were measured by gas chromatography (Hewlett Packard 6890, equipped with auto sampler and cross-linked polyethylene glycol, [??] 0.53 mmx30 m size FFAP
column; column temperature: 120[degrees]C, injector temperature: 265[degrees]C, detector temperature: 240[degrees]C).
Lactic acid in samples was determined in aqueous extracts by means of a GLC with a semi-capillary FFAP
(nitroterephthalic acid-modified polyethylene glycol) column (Hewlet-Packard, Wardbronn, Germany), over a temperature range of 45 to 230[degrees]C.
