Children scissors are a hot topic among parents and teachers alike; children love crafts and it`s a joy to see children expressing themselves creatively. But most such projects involve the use of scissors, and scissors can be dangerous. Even with all the attention on safety these days, there are thousands of scissor injuries-primarily cut fingers-sustained by young children each year. So what to do? When you`re looking for the ideal scissors for children look first for innovative blade safety technologies like Slice`s finger-friendly grind. Also look for a model that is designed to be ambidextrous and can easily be handled by small hands, with a comfortable grip. Children`s scissors also need to have a small blade area and, very important, the tip must be blunted. Put all that together and you`ve got children scissors that will let creativity blossom safely, effectively, and abundantly.

An ion chromatography method for the rapid determination of lactose content in lactose-free foods and beverages was established. "Hamilton RCX-30-250 / 4.6 was used as the anion exchange column, NaOH (150 mmol / L) was used as the mobile phase, and pulsed amperometric detection was used. The method has a linear correlation coefficient r of 0.9999, a relative standard deviation of 1.25%, and a sample recovery rate of 94.3% -105.7% when the linear range is 5-50 mg / L. The analysis and display methods for 8 lactose-free foods and beverages The accuracy and precision are good, and the electrochemical detection greatly improves the sensitivity for the determination of low content of lactose. The result proves to be a simple, fast, high sensitivity, and good anti-interference analysis method.
