您是否曾经因为如下原因重复进行样品分析:

利用TruFlo样品监视器上的数字屏幕,您可以始终知道进入雾化器的样品汲取实际速率。这可以改进结果的可重复性,减少由于雾化器阻塞、泵导管磨损、泵导管卡箍压力错误而进行重复测量的需求。而且硼硅酸盐玻璃管道可确保没有记忆效应或样品交叉污染。如果样品汲取超过您指定的范围,TruFlo还会发出警报声。

如果您依赖雾化器的自然汲取,TruFlo同样是理想选择。许多操作人员,尤其是ICP-MS操作人员,利用自然汲取来消除蠕动泵噪音对其测量的影响。利用TruFlo,您可始终知道样品汲取量大小,如有任何改变可立即采取纠正措施。您还可以记录样品流,这可确保自己每次使用相同的样品流。

实际样品流显示在TruFlo的内置数字显示屏上,还可以在您的电脑上显示一个样品流随时间变化的图形。

您可以设置可接受样品流范围的上限和下限。

如果样品流超出可接受的范围,您会看到屏幕上出现警报,同时听到警报声。
如果样品流由于阻塞或泄漏受到限制,就会出现这种情况。泵导管磨损时也会出现这种情况。泵导管替换时间经常过早或太晚。

您始终知道实际的样品流,并且不需要担心根据样品流转换泵转速。

实时样品流显示可让您优化蠕动泵导管上的压力,帮助您最大程度的延长导管寿命,改善分析精度。太大压力会导致导管更快磨损,造成更多噪音。太小压力可能导致紊乱的样品流。上方显示屏中,每个箭头处卡箍旋紧了半圈。

TruFlo规格

Non-aqueous solutions

The TruFlo is normally calibrated for aqueous solutions. With non-aqueous solutions, it can be reliably used to detect any change in the sample flow, but the actual flow reading will not be correct. If you routinely run non-aqueous solutions you can order a TruFlo calibrated for your specific application. You will need to specify what solution you are using and the TruFlo will be supplied pre-calibrated for your solution. When you order the TruFlo, simply add:

Part number 70-TFCAL, TruFlo calibration service.

QA Kit

The QA Kitis a convenient package combining the TruFlo Sample Monitor, Inline Particle Filter, Eluo Nebuliser Cleaning Tool and Eluo Adaptor for Inline Filter.

The QA Kit enhances the day-to-day reproducibility of your results and greatly reduces the chance of a blocked nebulizer.

客户评论

The NEW TruFlo system is working really well.

University biology laboratory - Australia

If sample flow rate is suspect for some reason, one way to monitor it would be with Glass Expansion's TruFlo Sample Monitor.

Environmental consultant - USA

(In reference to the TruFlo) It works exceptionally well. I have two units connected to ICPs and have saved a great deal of troubleshooting time because of them.

Manufacturer - USA

(In reference to the TruFlo) A nice piece of kit to help with sample intro trouble shooting.

Minerals laboratory - Australia

(In reference to the TruFlo) No need to convince me - I consider this an essential tool for every lab that uses ICP-OES, ICP-MS.

University Analytical Chemistry Department - Canada

The TruFlo from Glass Expansion is a great diagnostic tool for flow rate control.

QC Laboratory - USA

We like the TruFlo monitor. It has helped us on a number of occasions to track down some minor issues and we use it constantly while running our ICP.

Oil company - USA

I just had a frustrating fiasco with a happy ending that might prove helpful to others. We were experiencing random high drifts (>10% over 5 minutes) ... I purchased a liquid flow meter from a popular ICP supplies vendor and installed it on the carrier line. Sure enough, the flow rate was making fairly abrupt changes consistent with the observed drifts in the ICP emission. I finally figured out it was a worn teflon rotor in the FAST switching valve ... I have found the sample flow meter to be a very handy diagnostic tool ... It is the TruFlo from Glass Expansion. I saw it at Pittcon and remembered it when the problem arose.
