I am aware there has been no official announcement of a successor to the XT, but what does the community here think about how many years are left before this happens? Edit: should mention we&#039;re looking at H1 2027 purchase so whatever lifetime the XT has today, subtract 1 year from that. submitted by \/u\/TheProudCanadian [link] [comments]<\/div><\/li><li class='wp-block-rss__item'><div class='wp-block-rss__item-title'><a href='https:\/\/www.reddit.com\/r\/analyticalchemistry\/comments\/1sm9iaz\/pfas_in_drinking_water\/'>PFAS in drinking water !?<\/a><\/div><time datetime=\"2026-04-15T15:33:19-05:00\" class=\"wp-block-rss__item-publish-date\">April 15, 2026<\/time> <span class=\"wp-block-rss__item-author\">by \/u\/alchemicdpak<\/span><div class=\"wp-block-rss__item-excerpt\">submitted by \/u\/alchemicdpak [link] [comments]<\/div><\/li><li class='wp-block-rss__item'><div class='wp-block-rss__item-title'><a href='https:\/\/www.reddit.com\/r\/analyticalchemistry\/comments\/1skc9iz\/sample_stuck_in_xcalibur_sequence\/'>Sample Stuck in Xcalibur Sequence<\/a><\/div><time datetime=\"2026-04-13T14:20:40-05:00\" class=\"wp-block-rss__item-publish-date\">April 13, 2026<\/time> <span class=\"wp-block-rss__item-author\">by \/u\/Training-Resist-2745<\/span><div class=\"wp-block-rss__item-excerpt\">submitted by \/u\/Training-Resist-2745 [link] [comments]<\/div><\/li><li class='wp-block-rss__item'><div class='wp-block-rss__item-title'><a href='https:\/\/www.reddit.com\/r\/analyticalchemistry\/comments\/1shlymp\/classical_piston_pipetting_vs_pressureoverliquid\/'>Classical piston pipetting vs pressure-over-liquid pipetting \u2013 which would you choose?<\/a><\/div><time datetime=\"2026-04-10T13:03:51-05:00\" class=\"wp-block-rss__item-publish-date\">April 10, 2026<\/time> <span class=\"wp-block-rss__item-author\">by \/u\/Federal-Scratch-2500<\/span><div class=\"wp-block-rss__item-excerpt\">1.
