加拿大Questron?
加拿大Questron成立于1989年，致力于制造和銷售并提供實(shí)驗(yàn)室分析儀器運(yùn)用于環(huán)境，醫(yī)藥，自然資源，生產(chǎn)，農(nóng)業(yè)，政府實(shí)驗(yàn)室，教育等各個(gè)領(lǐng)域。
傳統(tǒng)的敞開式消解系統(tǒng)來做樣品前處理容易受到環(huán)境等因素的影響，較容易產(chǎn)生樣品間的交叉污染。然而，隨著計(jì)算機(jī)科技的發(fā)展，和微波技術(shù)的產(chǎn)生和發(fā)展，利用微波作為加熱源，大大節(jié)省了樣品前處理的時(shí)間，為樣品分析提供了便利。我們的 QWAVE 1000 微波消解系統(tǒng)可以提供一個(gè)安全的便捷的方法進(jìn)行微波消解。用相同的腔體，配合不同的消解管(UHP, VHP, 或LVHP 消解管)滿足不同的客戶需求。 如果您的實(shí)驗(yàn)室需要通過不同級(jí)別的微波系統(tǒng)來滿足消解，滿足消解后的樣品得出可靠的數(shù)據(jù)，運(yùn)用不同的方法。QWAVE 1000 是較好的選擇。這些消解的樣品，是運(yùn)用定時(shí)控制進(jìn)行微波加熱處理過程。
