腳下一片黃土,孕育了一代又一代人。土壤在維系人類生存方面,起著至關(guān)重要的作用!土壤學(xué)家常常將土壤比作地球的“皮膚”,作為覆蓋在地球表面的一層松散物質(zhì),人類的生活一直依賴于健康的土壤和它所滋養(yǎng)的生命。然而,土壤可以通過(guò)多條途徑對(duì)人體健康產(chǎn)生正面或負(fù)面的影響。
土壤通過(guò)食物鏈提供人體需要的礦質(zhì)營(yíng)養(yǎng),來(lái)自于土壤的化學(xué)污染、物理污染、放射性污染......卻通過(guò)食物鏈影響著人類的健康。我們可以看到,新冠肺炎疫情引起了社會(huì)各界對(duì)食物安全的高度重視。一日三餐,我們離不開糧食,糧食生于土地。土壤學(xué)家在土壤資源與管理、土壤肥力與調(diào)控、土壤環(huán)境與健康、土壤生物與安全這幾個(gè)領(lǐng)域也是重點(diǎn)研究領(lǐng)域。
近年來(lái)國(guó)家先后發(fā)布了《土壤污染防治行動(dòng)計(jì)劃》和《十三五生態(tài)環(huán)境保護(hù)規(guī)劃》等重要政策文件,對(duì)土壤環(huán)境監(jiān)測(cè)提出了若干新的需求和要求。為貫徹落實(shí)國(guó)務(wù)院、生態(tài)環(huán)境部有關(guān)精神,進(jìn)一步做好新形勢(shì)下土壤環(huán)境監(jiān)測(cè)工作,了解國(guó)家土壤環(huán)境監(jiān)測(cè)管理需求,提升土壤環(huán)境監(jiān)測(cè)技術(shù)和管理水平,掌握土壤監(jiān)測(cè)技術(shù)方法。由河南省分析測(cè)試協(xié)會(huì)主辦的“2020年河南省土壤環(huán)境監(jiān)測(cè)技術(shù)培訓(xùn)大會(huì)(鄭州站)”,于2020年7月24日在河南省鄭州市成功舉辦!上海凈信也參加了此次會(huì)議。
上海凈信這次攜帶了土壤樣品前處理的人氣產(chǎn)品—行星式球磨儀參會(huì)。JX-4G行星式球磨儀可以在短時(shí)間內(nèi)將樣品研磨至納米級(jí)別,該儀器適合對(duì)軟性、中硬性、及硬性、脆性樣品進(jìn)行研磨(干磨或濕磨)及混合處理,并且保證研磨結(jié)果具有可重復(fù)性。能應(yīng)用在理化分析前處理、膠體研磨、新型材料和機(jī)械合金的制備等方面。
行星式球磨儀
這款儀器的主要優(yōu)點(diǎn)是:適合長(zhǎng)時(shí)間制樣及連續(xù)運(yùn)行轉(zhuǎn)速可調(diào),運(yùn)行平穩(wěn);可將樣品研磨至微米級(jí)(干磨)及納米級(jí)(濕磨)的細(xì)度;自動(dòng)反向運(yùn)轉(zhuǎn),防止樣品集聚6種不同材質(zhì)研磨罐可供選擇;先進(jìn)的操作界面,簡(jiǎn)捷方便。在土壤樣品前處理這塊,上海凈信行星式球磨儀是比較出色的。
作為中國(guó)多樣品組織研磨儀及冷凍研磨儀的創(chuàng)*者,上海凈信專注在樣品前處理的領(lǐng)域,不斷更新和研發(fā)出更多的樣品前處理儀器。7月29-31日上海凈信將攜帶多款人氣產(chǎn)品研磨儀及新產(chǎn)品亮相“廣州國(guó)際分析測(cè)試及實(shí)驗(yàn)室設(shè)備展覽會(huì)”。誠(chéng)邀您參加!
