沉積物柱狀取樣器/柱狀采泥器 Sediment Corer 沉積物柱狀取樣器用于從軟的、沙質(zhì)和中等硬度的水體底部取樣。 沉積物柱狀取樣器使用非常簡單。既可以從淺水中取樣,也可從 深水中取樣??筛鼡Q取樣管長度600mm,內(nèi)徑72mm。 當(dāng)取樣器進(jìn)入水中時(shí),透明樹脂玻璃管頂端的塑料閥門會(huì)打開, 確保水可以自由流過取樣器管。 沉積物柱狀取樣器可通過用手推或者自身重力插入采樣底部。 當(dāng)采到所需的樣品室,將取樣器從沉積物中取出,在上升過程中, 取樣器頂端的閥門會(huì)由于水壓的作用而關(guān)閉。向上移動(dòng)產(chǎn)生一個(gè) 真空作用,使得樣品保留在管中而不會(huì)損失。 當(dāng)取樣器從水中取出后,通過一個(gè)活塞將樣品取出進(jìn)行分析。 沉積物柱狀取樣器/柱狀采泥器訂購信息: 437 400 沉積物柱狀取樣器(柱狀采泥器),包括下列組件: - 1個(gè)取樣管固定器, 凈重4.5kg - 1根透明取樣管, 長600mm×內(nèi)徑72mm, 凈重0.8kg - 2根鎖繩 - 1個(gè)塑料頂 - 1個(gè)密封帽 - 1根活塞桿 - 1根推桿, 不銹鋼材質(zhì), 凈重1.5kg 437 400/S 沉積物柱狀取樣器(柱狀采泥器),包括下列組件: - 1個(gè)取樣管固定器, 凈重4.5kg - 1根不銹鋼樣管, 長600mm×內(nèi)徑72mm, 凈重5.3kg - 2根鎖繩 - 1個(gè)塑料頂 - 1個(gè)密封帽 - 1根活塞桿 - 1根推桿, 不銹鋼材質(zhì), 凈重1.5kg 437 405 替代取樣管 有機(jī)玻璃材質(zhì), 透明,長600mm×內(nèi)徑72mm 437 406 特殊取樣管 不銹鋼材質(zhì), 長600mm×內(nèi)徑72mm 437 410 推桿 不銹鋼材質(zhì), 凈重1.5kg 固定在鐙索上,進(jìn)行手動(dòng)采樣 代表文獻(xiàn): 1.Nicola Cardellicchio, Silvano Cavalli & Pietro Ragone,1996.Supercritical Fluid Extraction of Polycyclic Aromatic Hydrocarbons (PAHs) in Marine Sediments and GC-MS Analysis.Polycyclic Aromatic Compounds.9(1-4):365-372. 2.W Brack, A Paschke, H Segner, R Wennrich, G Schüürmann,2000.Urease inhibition: a tool for toxicity identification in sediment elutriates.Chemosphere.40(8):829–834. 3.J.M.
