First, 2 principles of food samples by hydride generation atomic fluorescence spectrophotometry after wet digestion or dry ashing after adding thiourea pre-reduction of pentavalent arsenic to trivalent arsenic and Adding boron hydride or potassium borohydride reduction of hydrogen arsenide, by loading the silica atoms of argon 松开间歇机构与链轮轴的联结套进行调整，使动平台由上止点下降7-8mm(加工瓦楞纸时应10-15mm)左右时，牙排开始运动为好。 1.2.4润滑压力不足 本机器有润滑油压力不足故障显示。如出现警告，首先要检查过滤器是否堵塞，可以用汽油清洗过滤网。如油量不足，请按油标指示加油。检查油管是否变形或堵塞，检查调整开关压力设定压力是否正确。 1.3收纸部分 收纸部分的主要故障是收纸不齐或收纸散版: 1.3.1纸张收不齐: 最初纸张收不齐主要是因为收纸台开始时与侧齐纸板及前后齐纸板下沿间隙过大所致。只要按微升按钮SB36，将其往上适当升高即可。如果在收纸全过程中收纸不齐，则可能收纸台自动下降太大，此时可以适当减小收纸处自动降定时器的设定值，将下降距离适当缩小既可。另外在加工薄纸时也容易造成收纸不齐，此时应适当降低机器速度。 1.3.2收纸散版: 对收纸部分扶纸毛刷，当扶纸毛刷动作与纸张运动不协调是即夹纸力量过大或夹纸时间过早均容易造成模切后纸张的撕裂，此时应调整扶纸毛刷的动作时间及压力，使毛刷夹持纸张的三分之一，并且压力要小，能将纸张扶平即可。 2机床的保养和润滑 新机器使用一个月后，须重新更换润滑油，然后进行正常使用。 操作人员要准备润滑油的安全技术说明书(MSDS)，要认真阅读技术说明书，了解盒掌握化学品的危险性，并根据使用的情形制订安全操作规程，选用合适的防护器具。安全技术说明书(MSDS)要放到容易拿到的funnel, add water to the 20mL.

In the sample digest solution, reagent blank solution and lead plus 2mL in standard solution of ammonium citrate (20g/L), 1mL hydroxylamine hydrochloride solution (200g/L) And 2 drops of phenol red indicator solution, ammonia (1+1) to the red, plus 2mL potassium ferricyanide solution (100g/L), and mix. Plus 5.0mL II-dithizone with fluid, violent shaking 1min, static after stratification, chloroform layer through cotton wool filters into the 1cm in the Cuvette, to adjust the zero point in trichloromethane 510nm wavelength absorbance measurement, minus zero tube after each point, draw standard curve or calculate a regression equation, sample compared with the curve.cV1-the total volume of the sample digest solution, mL; V2-sample digestion liquid for measuring volume, mL. Results statement: report parallel determination of the arithmetic mean of the two valid number. 24 allow relative difference ? 10%. Detection of arsenic in the sixth chapter of food (Advanced) 1 scope this standard specifies a method for the determination of total arsenic in food. This standard applies to the determination of total arsenic in food. The method detection limit: by hydride generation-atomic fluorescence spectrometry: 0.01mg/kg, linear in the range of 0ng/mL~200ng/mL silver salt method; 0.2mg/kg; arsenic spot method, 0.25mg/kg; borohydride reduction colorimetric method: 0.05mg/kg.
